U.S. DoD Commits To IPv6
babaloo writes "According to this
article the U.S. Defense Department wants to move it's entire network to IPv6 by the year 2008. Will this be what pushes at least U.S. based companies and providers to actually convert over?" It's definitely a shot in the arm that IPv6 needs. This seemed to be more of a priority back when NAT was much less prevalent, but it seems we'll eventually find ourselves on IPv6, even if we drag our feet there.

Yeah, but.. Didn't the government want us to be totally metric by now also?
Maybe the white house could push this through.
BTW does Bush even know what IPv6?
I called up one of my customers ISP's for support and asked if they support IPv4 and they said no.
For those not in the know, here is a brief article Explaining the benefits of IPV6.
.....every second until the day IPv8 goes into effect, not to mention every person alive, every toaster making toast, every toilet still flushing, and every bullet fired. Maybe this is why the DoD wants IPv6... No not for toilets, internet enabled bullets!!

I think it is asking too much for your average home user or even small sys admin to make this shift - unless it comes as "standard" in Windows (yes, I hate it too) or the key 'nix distros
Its pretty much a fact that most internet innovations are due to military and pornography pushing early use. IPv6 is definitly going to happen now.

Now if we only could see some commitment from other than largely overfunded organizations and the people that actually build the ipv6 products...
I visit /. about once every 2 days, and even I know this is a repost :)
And now you're getting a lesson on redundant posts, as approximately half of the 15 talkbacks posted so far say the same thing and have the same link...
It wants its story back.
I bet the editor who posted the story is modding down all the "you dumbass, this is a repost" comments. Hooray for unlimited mod points for editors.
What are they going to do with all those IP addresses? Oh wait, I know. A trillion nano-machines flying around the Iraqi country side, injecting anthrax into Saddamic supporters...
IPv6 has enough IP's to identify each unique second until IPv8 is released.
IPv8 won't be released until all IPv6 addresses are used.
The longer it takes for IPv8 to be released, the sooner it will happen!

But that's just my two cents.
Good that the DoD is still support projects that came about from their original idea, ARPANET, or as we so lovingly call the contemporary version- the internet.

Why would it be? I assume most US based companies and providers don't have many connections to the DOD network :) ;)
When a: there is a decent amount of IPv6 only content, and b: when the most widely used OS in the world ships with it enabled by default, (ipv6 install doesn't count here) then it might start taking hold. But it's a chicken and egg situation at the moment. That autopr0n guy should switch his site to IPv6 only, and force his viewers to start using IPv6 (or IPv6-over-IPv4)

Why don't we charge people $1 to renew an IPv4 address after 50 years. Then we can encourage people to switch to IPv4.
Lets hope we don't rush into things and end up with another one of these with our nations secrets as opposed to students psych evals :\

>> U.S. DoD Commits To IPv6
Washington, DC - June 26, 2003 - Dept. Of Defense in charge of security and defense for the United States Of America will be going over budget on an IPV6 upgrade. The majority of costs will be involved in training staff to count to the number 6. Previous training to count up to 5 was thought to be years ahead of its time since the DOD believes IPV5 would come after IPV4.
Why don't we charge people $1 to renew an IPv4 address after 50 years. Then we can encourage people to switch to IPv6.
IPV6 is the Hurd of networking protocols!
C - A language that combines the speed of assembly with the ease of use of assembly.
This seemed to be more of a priority back when NAT was much less prevalent
Since several states have already banned NAT, and several more are moving in that direction... perhapse IPv6 will be necessary much sooner than we think.

"move it's entire network to IPv6 by" It is "its". "it's" is a contraction meaning "it is". the possessive form of its is "its".
I know its a slim possibility, but here is the text:
Defense Department Will Require IPv6 Compliance, Says DoD's John Osterholm
Thursday June 26, 3:43 pm ET
Citing National Security Concerns, Osterholz Says $30 Billion DoD IT Budget Will Only Buy Network Technologies That Are IPv6-Compliant Starting in October 2003, With Full Integration by 2008
SAN DIEGO, CA--(MARKET WIRE)--Jun 26, 2003 -- IPv6 SUMMIT -- John Osterholz, director of architecture and interoperability for the Department of Defense, told a gathering of technology elite that the DoD would phase out purchases of IPv4 network technologies by this fall and would instead begin trials of equipment and applications based on the new IPv6 protocol for the Internet within 30 days. He said the move was intended to build a "Global Information Grid" of Net-Centric operations that was fully distributed, available and secure. He noted that this would be an important part of fighting terrorism and ensuring homeland security.
"Al-Qaeda maintains a low profile and is highly distributed," noted Osterholz. "Until recently, we had no capability to operate similarly, and we understand it is an important capability. They were Net-Centric, we were not. Their command and control capability requires us to have a similar capability." Osterholz added that both Slashdot and the Linux community itself was rife with pedophiles and homosexuals.
In his keynote, Osterholz laid out his plans for moving the entire DoD information technology infrastructure -- the world's largest, with an annual IT budget exceeding $30 billion -- into full IPv6 compliance by 2008. This represents an unprecedented move by the Defense Department to approach the entire commercial Internet infrastructure, which includes IPv6 Summit sponsors Cisco (NasdaqNM:CSCO - News), Hewlett-Packard (NYSE:HP - News), Nokia (NYSE:NOK - News) and the Verio division of NT&T (NYSE:NTT - News), with detailed instructions on the networking standards it plans to support.
Historically, the DoD has created or commissioned vendors to build proprietary infrastructure. But the DoD's need for global, immediate access to secure, real-time information has moved the department from an infrastructure of data links between proprietary systems to a secure global enterprise built on the next generation of open systems. Osterholz called this system the Global Information Grid (GIG) and said one of its primary DoD uses will be "predictive battlespace awareness" that combines intelligence and operations technologies in a connected, real-time environment.
"Our soldiers need better information in order to make better decisions -- who to help and who to kill," continued Osterholz. "The lack of security and flexibility in the current IPv4 protocol is a drag on our wing. This isn't about do you trust the Internet for your kid's homework, it's do you trust your kid's life. If we fail, people die."
About the Global IPv6 Summit
IPv6 stands for Internet Protocol, version 6. The current Internet has been using the same technological protocol since it was invented in 1969 and is rapidly running out of domain addresses. IPv6 will allow an expansion from the Internet's current limitation of 4 billion addresses (to a new limit of 380,000,000,000,000,000,000,000,000,000,000,000,00 0, which is a number so great it could supply each person living today with more than 4 billion addresses each). IPv6 also allows for greater built-in security, as well as vastly improved support for mobile users and wireless devices.
The North American IPv6 Global Summit, which started today and continues through Friday, is a world-class conference that is primarily subsidized by the sponsors and SDSU. The Internet Society and 12 other technology and standards organizations endorse it. The Summit also features speeches by Jawad Khaki, Corporate Vice President, Microsoft; Larry Smarr, director of Cal-(IT)2 at the University of California, San Diego, plus many other leading figures
You know, call me weird or something, but I happen to like NAT and, well, pretty much fully understand IPv4.
:)
... learn it.
:)
Yeah -- I know how to use a Linux box as a decent router and setup Firewall's as needed, etc.
The fact that I'm not doing anything SERIOUSLY complex helps:
- Web servers (port 80 and 443)
- imaps (port 993)
- ssh2 (private port with honey-pots all over
- other misc needed ports and tunnels as well.
ONLY ports I specifically opened up and re-directed are available to the general Internet. Firewalls run internally as well, but many more services (lpr, smb, hell IPX is stilled used/preferred for accounting work)...
With IPv6 I'm probably going to go the route of:
1) Ok -- I *basically* understand it, but honestly haven't wrapped my brain around it
2) Try and get a few IPv6 addresses as needed
3) Update front end router to use it work with it.
4) Tunnel it back into my IPv4 network per port as needed. IPv6 NAT if you will...
I really don't want anything/everything directly connected to the Internet. At anytime. Except the Internet network router. These ISP's selling "Windows DSL modems" where it plugs directly into USB or the Ethernet is NUTS, IMHO.
Once in a blue moon I'll come across a Linux box that has ftp (for example) enabled and there really isn't the want/need for it. Oops, not Firewalled either... Glad it wasn't directly on the 'Net (!)
Even when the need _has_ arisen to put a box completely on the Internet directly it's been easy enough to setup a 1:1 map on the router... While the video feed was going on I personally would be nmap'ing the box to double check the firewall settings...
Of course the problem exists because, well, it is TOO easy to get on the Internet. Too many have no clue what they are doing, but they get email (!) Yeah. Those are the ones spreading virus' and not knowing it or have a hacked box spewing spam around the world. Some problems could also become moot with IPv6 in regards to security and accountability...
!fp
i've been hoping SOMETHING would catch on with this... it's a move that's been needing some help for a while now...
I don't remember that. Can you point out a few references for me to paruse and post them here?
Won't we need IPv7 by then?
YOU SUCK BALLS!
IPv6 sounds great but I see that we will need more TLDs and a domain name will be absolutely necessary.
Frickin' Rainman will be the only one able to remember xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.
At least the giant corporations that are our new overlords will have to spend some serious $$$ to cover all the new 'name.new tld'. Perhaps after all this is done, they can work on flying cars. 'cause we are like 50+ years behind the times here, people.
But all that has to take a back seat to hard-to-remember IPv6.
Here's a plan, why don't we just take the internet away from all the AOLers, the Flash greeting card senders, the 'Great Story! Read this LOLRFLOLRLOL!!!!'ers, Zone Bejewled players and the cheaters at Counter Strike and we'll have enough IPs for all of the elitist bastards that are going to make my toaster talk to me.
Tell you what. I will trade all my IPs (192.168.x.x) for a friggin' flying car.
Let's make it happen. I'll even have a bumper sticker, "IPv6, but my doctor says I'll be fine!" with a smiley!
Gimme my flying car.
if it were not for the increased awareness of security, this would never had happened.
There are now explosive rounds, fired from a gun, that will fly a designated distance and explode. Really useful for shooting people hiding around corners, behind walls, etc.
They are still in prototype now, and I think are part of the LandWarrior system.

Cisco has finally released IOS 12.3 which has full support for IPv6 in a production IOS train (see http://www.cisco.com/warp/public/732/Tech/ipv6/ ) - IPv6 has been in the 'T' train IOSes for some time. Their support now makes full use of hardware acceleration and looks very complete.
Juniper have had IPv6 in production JUNOS releases on the M-series/T-series for quite a while.
Most other vendors already have production IPv6, so in reality the router vendors aren't a roadblock. The same is now true for host OSs - Linux, Windows XP and modern Unixes have had IPv6 for a while as well. The real issue is getting applications ported (not that hard) and networks deployed.
Mod Up Funny
What I found more interesting than the 2008 date is the purchasing guideline that products purchased need to be IPv6 capable/compliant after October this year.
That doesn't just apply to IP device drivers, but implies that any application that deals with IP addresses, including any networked app, needs to "grok" IPv6 addresses, have expanded buffers for longer addresses, etc.
It means that the infrastructure, from DHCP to DNS to SMTP to syslog and Apache all need to be IPv6 ready in order to make it to the approved products list.
There are still a lot of products out there that don't or can't do that.
It is definitely a good thing, but the US isn't going to shift to IPv6 just because one government department has decided to use it. It will happen by people getting involved with IPv6. Jump on the 6-bone today.

It's a good thing I moved to reading /. only once a week... saves me time and I don't miss anything.
How could we forsee a use for 3.8e38 addresses? 4 billion per person? Can computers handle this? Will they be able to? I don't really know how IP works (short of every computer is assigned one) - maybe someone can clue me in or link me? I imagine the IP is stored in each computer somewhere. Storing a unique number that large is going to suck up a lot of memory.
Remember, IP n00b - don't yell at me.
Oh, I thought at first that it was about this DoD.
[note, it really should be NAPT (network address and port translation), NAT alone is pretty harmless]
Let's say I'm the author of a voice over IP application on a platform that supports IPv6, like, say, Mac OS X. I get myself a NAPT-replacement box that I stick on the edge of my home network. It assigns an IPv6 address to each of the inner systems using 6to4. Then, when my caller wants to try to phone me, I give her my IPv6 address. She connects to that address and her magic box sets up an IPv6 tunnel to my magic box automatically. Then my magic box forwards the packets to the right machine in my network.
Add a firewall to that, and you've got something that replaces NAPT.
You could keep IPv4 NAPT as a legacy feature for inside hosts and applications that don't support IPv6 yet. But apps that do support IPv6, would not have to do any work to traverse the NAPT.

...they start doling out blocks of 2^32 addresses to every company that asks.
We wouldn't need all of IPv4's space for a long time, if only they were assigned one (or, at most, 256) at a time.

Black holes are where the Matrix raised SIGFPE

IPv6 is picking up steam, another push like this is going to make it appear in all new computers a little bit sooner.
In every installation I've rolled out in the last few years, I've specced IPv6 support. Every network, router, interconnect, carrier and transit has had IPv6 working. Not always working very well, but enough that people didn't notice whether their traffic went over IPv6 or v4.
Solaris has had IPv6 for several years, and the current release its on by default, plug it into a network with an IPv6 router and it works. M$ is playing catch up by including it natively in XP, but it still takes some tweaking. The linux distros will have to start making it enabled by default (no more kernel recompiles), but that may be happening as I type this. More and more applications are being written as fully IPv6 aware, and most of the traditional apps like ping, FTP, traceroute and SSH are now re-written to use IPv6 when a AAAA record is returned from a DNS lookup. There still is a lot of work to be done, like fully working dynamic DNS updates, and DHCPng, route servers, and a free (as in everything) certificate system for IPSec. Every new release of every browser should check for IPv6 and use it whenever possible, M$ claims that will happen starting with their next desktop releases.
Where I've seen the most far-sighted development is in the newest generation of GSM mobile phones. All the big players are including IPv6 in their current handset designs, and the carriers are now developing value added services to sell. So its not just each phone is individually addressable, but can roam onto competing carriers networks and still have a globally accessible address. Internally, every carrier in Europe with 2.5G/3G services is running IPv6 for everything (except for a few dinosaurs about to be extinct). The other big area is giving each credit card with a smart chip (anti-fraud and verification chip) a range of IPv6 addresses. When the card is put into a reader or used for an online purchase, the chip will actively participate in the verification step by being uniquely addressable and requesting end-to-end encryption. There were several card manufacturers showing off their tiny IPv6 stacks at a recent smartcard trade show.
As I've pointed out in a post months ago, many ISPs here in Europe are making IPv6 available for early adopters, in the hopes of riding the next wave to some higher margins. I've had clients ask me for advice on getting onto the "new internet", because they didn't want to get left behind on the "old and obsolete internet". Then I point out how they are already on it, and my installations use the "new internet" whenever possible.
IPv6 is here, it works, and soon consumers will make it a "must-have" item when buying a new computer. When that starts happening, then techies with a few years of solid IPv6 experience will be sought after for their skills.

Hemos is like...sci-fi fans;he thinks technology is cool, but he hasn't bothered to understand the science it's based on
Crucially, in the header for the new protocol version there are 128 bits for senders and recipients. That equates to several quadrillion IP addresses for every individual alive.
:(
oh well, w/ that many available ip addresses, i'll hopefully be able to get a static IP thru my service provider...(if several quadrillion time the worlds population is enough to allow for that)
Damn, thats it...I was hoping for at least a quintillion

Oddly enough, NAT's natural firewall characteristics generally make life hard for filetraders behind them, or for any other program that needs to allow people outside the NAT to connect to the people inside, especially on unusual ports. Sure, you can always forward ports - provided you have access to the NAT configuration and you don't have multiple people behind them needing the same ports.

It's not enough i tell ya.

Sorry, man.
Cue rant . . .
Actually it's the 20mm component of the former Objective Individual Combat Weapon program, part of the Small Arms Master Plan, now dubbed XM29. Essentially this weapon combines a variation on the G36C for underbody (almost a submachinegun) with an overslung semi-automatic 20mm explosive round (grenade, really) that can be set to burst at a given range by pointing at the object to burst upon, then increasing the range up a meter or down a meter.
There are some problems with this when compared to the M16A2 / M203 40mm underslung grenade launcher combination currently in use (or increasingly the less successful M4/M203 combo).
First of all, the 'normal' rifle portion (the G36C) sports a barrel so ridiculously short that the rounds do not exhibit the fragmentation behavior desired. A 10" barrel is insufficient for accelerating a 5.56x45mm round to the point where it can be truly effective in outdoor combat. The M16 family used a 16" barrel for a good reason - there's a full 75~100m/s muzzle velocity advantage over the 11" Colt Commando. Many sections of the Armed Forces have refused to or have been extremely reluctant to adopt the 14" barreled M4 for this same reason. Size does matter here, because longer barrels mean the bullet is in a sealed chamber being accelerated by explosive gases for a longer period of time and 10" is simply not enough.
Beyond this, there are many questions regarding the utility of the 20mm explosive round component itself. Everything from fears regarding any failure of the electronics system to, again, lethality. The single-shot breach loading M203 40mm grenade launchers currently in use provide an effective fatality radius of approximately 5m, and will wound most individuals within 15 meters of impact. The 20mm grenade, however, is the minimum size of projectile which can carry a useful explosive load and is loaded with circuitry to boot. The fatality radius is 1~2m with a 5m wounding radius. On the other hand it is far more accurate than the M203, but US soldiers are nothing if not well trained.
Current plans are for 45,000 units at a cost of $10,000 each (several times the cost of an M16/M203 combo) by 2009, and the general idea currently is to outfit active squads with one such weapon each.
The SAMP also includes a potential replacement for the Mark 19 Automatic Grenade Launcher (uses special high-power 40mm grenades) called the Objective Crew Served Weapon that utilizes 25mm grenades. This one may show significant merit as the possibility of an infantry-portable automatic grenade launcher is simply too good to pass up.

OK, this is very funny. IP addys for every bullet. But listen gang, the ISPs have been tight fisted with IP addresses for so long that most of you young-uns don't even remember the day when anyone with a router could count on a Class-C or even B to themselves. Those days are LONG gone; now you get DSL and you pay for ONE frigging static IP address, and if you want anything like a big chunk of a Class-C you have to pay serious cash. Monthly. And upgrade? You want more? Well all the IPs on either side of your teeny tiny block were sold to other shmoes already, so if you want more you get a whole new block. So you better get more than you think you will need...ever...or else everytime you run over your public IP space you will need to reconfig your entire public facing Internet presence to a new block.
But you know what, that's not really a technology limit, that's a BUSINESS MODEL.
Watch this. When they finally go over to IPv6 and later install your new DSL, know what the knee-biting bastards will do? First, they will charge you MORE for a basic DSL with dynamic IP because now it is the new-fangled IPv6 (new=$$$). Then they will assign you a SINGLE IP addy from their store of 128 trillion. And they will assign IP addresses this way in SEQUENCE to all subscribers so that as soon as you get yours you are boxed in by other subscribers just getting theirs. You know they will, it will be a strategic decision to completely undermine the freedom you SHOULD have when there are about 1 billion IP addresses for every human alive on earth.
The only way around this would be to issue IP blocks to physical locations on the earth, so no matter where you are you have all the IP addresses reservered for that square meter of dirt, and if you have a large home/office/company then you have a big block indeed. ISPs would be forced to backbone their entire geographic area, including the whole planet if they are big enough.
As a business model it sucks big wind. But I like it as an end user.
Wire the planet. Freedom to connect! No more IP address space tyranny!!

For those not in the know, here is a brief article Explaining the benefits of IPV6.
One of the big differences between the GOSIP OSI stack (which failed in the market) and IPv6 (which might succeed) was that GOSIP was big, clumsy, generally didn't work, and didn't have lots of applications, while TCP/IP was much lighter weight and had lots of commercial support by vendors and lots of people really developing useful applications (like FTP and SMTP as opposed to X.400.) It's possible that the same thing will happen to IPv6, but if Microsoft and Cisco support it and the DoD's DNS servers support it, it's got a chance of working.

Maybe you read it the first time when it was called Pentagon Wants IPv6 by 2008. I know that Yahoo! isn't exactly known for their great reporting skills but come on folks... sheesh. And its dupes like this that keep my crummy news suggestions from getting accepted.
Second, that essay sucks. For instance, a pint is not 250ml, but 568ml. The reason people order pints of beer instead of 568ml (or even a half-litre) is mostly historical, but it's also because it's handy to have a nice short name for a measure you use often. If they had used metric for beer all along, then people would have needed a short nickname for a half-litre, and perhaps they would have called it a pint. It's the same way we call kilometres "clicks", and it has nothing to do with base 10, or fractions, or "number theory" as you say.
This guy goes on to say:
No, we are most certainly not back where we started from. If you like to give a name to 3/7 of a metre, that's your business, but I like the fact that I can do mental math in metric, and convert units just by sliding the decimal point.
For example, if I'm travelling at 31km/h, what is that in metres per second? It turns out the hardest part of that calculation is converting hours into seconds, which involves dividing by 3.6. As far as mental arithmetic goes, it doesn't get much harder than that. There's your precious number threory for you. And it only gets worse if you try to turn 31mph into feet per second.
In contrast, if my car uses 7.3 litres of fuel per 100km, what is that in millilitres per km? It's 73. It's so simple you can do it in your head, and get your answer with as much precision as you want, so long as you are capable of sliding the decimal point properly for each unit conversion.
Later, we find this demented little nugget:
The problem here, if you'll take a moment to think about it, is that the authors of these cookbooks are not using the metric system. If they were, the problem would disappear. (In fact, if they would use any consistent system, the problem would disappear.)
How the author manages to blame this on the metric system is beyond my comprehension.
The best part comes next. I think my whole attitude on this "essay" can be focused on this one small quote:
You don't need to read anything else in this essay---even the rest of this paragraph, where he goes on to say that people buy wood in 120cm lengths---because it's all here. Nobody cares if you can't divide a metre into 3, just like nobody cares if you can'

"No one will need more than 637 kb of memory for a personal computer"
"No one will ever need 3.4x10^38 IP addy's."
"the U.S. Defense Department wants to move it's entire network to IPv6"
It is entire network? No way!
Fucking moron.
Can we get the army to say they wont use mp3's and use some better and open standard? :) Maybe they could intimidate everyone else to do it... Oh the Americans have it, your country(army) is so third rate... Hey why not? I think other countries resent the Americans as controlling the world but are really falling over themselves to follow . Its halarious I think. So if they act ho hum and do it that much publicity isn't needed. Thats what other countries intelegence services are for, to work for you. Just like the cold war, they can take stuff out of the Wall Street Journal stick it in an envelope and stamp classified on it. By human nature its pretty much inevitable.
Oh and Yes, but how will this help me get more porn?
What is to prevent the independant ISPs from switching thier systems over?
.mil is going IPv6 in 2008, does that mean the rest of the net waits until then?
I believe that cisco already supports IPv6 on most (all?) of thier equipment. There are IPv6 packages for most OS, and you can support IPv6 and IPv4 simultaneously if neccessary.
Is it neccessary for the smaller guys to wait?
If
That seems a little ass backwards to me.
Read, L
Multicast exists in IPv4 as well, but no ISPs support it since no one's worked out a pricing model for it yet.
10 PRINT CHR$(205.5+RND(1)); : GOTO 10
It is not all ISPs that are for this.
Looking at the list of witnesses who were 'for' and 'against' the bill in Texas, it is the cable companies, and the RIAA that are for it, and Telcos (and many other sane people) that are against it.
Both the cable companies and the telcos are ISPs. One of the reasons the cable companies are against it is that thier business model (and as a result their network architecture) is predicated on a per machine fee; NAT gets around this. When too many people get on the local loop (and that loop is quite large) their network sux hind tit.
Telcos, on the other hand, are selling the idea of using NAT on their DSL networks (one package I saw included a Blue-Tooth device to connect multiple machines to the net in the home).
Telcos got it right and engineered for large bandwidth operations - they will soon be offering full duplex DSL (if they don't already) with static IPs.
Cable companies will continue to piss off their customers - unless, of course, they can force everyone else to play by their rules - so everyone can be pissed off at them...
How I agregate my network behind my firewall is my business; if a provider wants to enforce the idea of a completely open (open as in unsecure) network, then I will take my business to a provider who values my desire for security and privacy.

The more you explain it, the more I don't understand it. - Mark Twain
or is it a serious issue as ipv4
I was wondering if anybody had a good link to a plain understandable real world little theory as necessary document on IPv6. I found a tunnel broker, don't know how to use it, can't find reasonable documentation, (no, the IPv6 howto doesn't tell me what I'm looking for). I just want to assign my currently external IPv4 gentoo server at work a IPv6 addy. How do I do that, and, perhaps moreover, why would I want to (besides, heh, cool, I can ping this big blob of stuff I can't remember). And how will it eventually be implemented. Who will hand out IPv6 blocks? Like with IPv4 now?
I haven't posted in so long, my sig is out of date.
...was telling the audience (mostly non-technical) about IPv6.
He mentioned how many addresses, and then asked if anyone knew what that meant.
He said that it would mean there would be enough for every frickin appliance, and it could run Java on it, and did anyone know what THAT meant?
Of course no one was supposed to have any answers, it was almost all PHBs there (I got dragged along to man a cursed booth).
So I raised my hand and said "So you can get up in the morning and reboot your toaster?"
EVERYONE burst out laughing!
"Move it is entire network"? That doe'sn't make 'sense, at lea'st not in Engli'sh.
Think how much easier routing would be. Unfortunately, tracing would be just as easy...
We want new gear. Err, because, errr, Terrorism! Yeah! We want an internet just like the ragheads. Yee-haww cowboy! If we don't get some new toys there'll be terrorism!
I have only seen routers using multicast to communicate. There are almost no applications using it, and almost no firewalls permitting it.
Sounds longer. Must be better!
Japan has given a deadline of 2005 for IPv6 adoption. After that Europe and then, later, the U.S. will also start to adopt. There's a fresher article from this week, but I can't find it again.
Beta is broken and the link to classic doesn't work. Stop wasting our time or there won't be anybody left here.

I'm probably not alone in this -- I guess many people of my age (almost 40) have the same problem.
When I was in primary school, we never learned the imperial measurements (aka the English system, or whatever). We learned metric, because by 1980 the country was going to have converted, and there was no point in teaching something that was going to be obsolete in 6 years. As a result, unlike my parents, I never learned by rote how many gills there are to a peck, or more usefully, how many feet are in a mile. I learned something in school that I never used, and was surrounded by measurements that I was never formally taught.
As the previous poster pointed out, President Reagan suspected that metric was a communist/socialist plot against traditional American values and measures, and suppressed all funding for US metrication.
Since I'm not a complete idiot, I've been able to get by, but I still have to think hard about the boiling point of water in degrees F, or the number of yards to a mile. Similarly, although I know how many centimeters there are to a kilometer, I have a tough time visualizing either one, or relating to a weather forcast in Europe (or Canada!)
It's ironic, since the US was one of the first nations to adopt a decimal currency, getting rid of the pounds-shilling-pence-farthing system long ago.
We should be able to handle irational numbers. I dont think a third of a meter is a hard for any competent carpenter to figure out. Mark 33cm 3 mm and cut there. The cutting blade itself is 4 mm thick or so. That is as accurate as you proboble can expect. Millimeters are marked on most meter sticks and fractions to decimal conversion shouldn't overly stess anyone who passed high school as all you need to know is division. Anyhow in Canada it is interesting to note that the company I worked for used "stantard size" metric measurements that convert easily either way. Thus going to metric does force anyone to not use imperial to satisfy continuity for people. Imperial has different definitions in different countries. I dont like the ambiguity of Gallon. Maybe the US will reconsider.
As a real proposal!
1% of addresses are designated by latitude longitude; with 2 categories 1-permanent 2-moving.
Moving objects can aquire unused nearest latitude longitute addresses for x seconds.
The point isn't to cut the board into thirds, the point is to cut the board so it fits whatever the carpenter is trying to build! THAT'S WHAT RULERS ARE FOR. The board could also be 100cm long and you'd still be limited to the markings on your ruler to get within a 1/6th of CM or whatever the fuck your sticking point is.
Jesus fucking christ, I need aspirin.
