The exhaustion of IPv4 address space
FireFury03 writes "Cisco has an interesting article talking about estimates for the exhaustion of the IPv4 address space, and the inevitable move to IPv6. It predicts that the IPv4 address space will be exhausted in 2 - 10 years and suggests that it isn't worth trying to reclaim old allocations. With the mainstream use of IPv6 now potentially within the ROI period of many products the manufacturers need to start including support, but will the ISPs roll out native IPv6 networks before they absolutely have to? IMHO, ISPs providing native IPv6 support would be a Good Thing since it opens up the door for peer-to-peer technologies such as SIP without needing nasty NAT traversal hacks, but a major stumbling block seems to be a complete lack of IPv6 support on current consumer-grade DSL routers (tunneling over IPv4 is an option but requires more technical know-how from the end user)." Of course, Cisco may have some vested interest in driving up the IPv6-compatible router sales *cough*, but the bottom line is that the transition will have to happen at some point in the near future.
Interesting, but is 2 - 10 years as precise as they can be?
8 years seems to be a long time, to me...

Will *BSD die before the switchover to IPv6? Maybe a good Slashdot poll:
[ ] Yes
[ ] No
[ ] Microsoft
[ ] I don't know what IPv6 is, but I'll post anyway

2-12 years is as precise an answer as Rummy can give about the Iraq insurgency lasting. If it's good enough for the main stream media, it's good enough for average joe six pack me.
Dick "Netcraft" Cheney: I think IPv4 is in its last throes.
Saskboy's blog is good. 9 out of 10 dentists agree.
in 2 to 10 years lots of things will happen. some people will die, some will be born...
aw, c'mon...
in a month europe, brasil and a few other nations will force a global netsplit, so we'll have 2 "internets". double the address space for the same price, so this prediction is not only imprecise, it's useless!
my R$0,02.
What ? Me, worry ?
I have my IPv4 address. Why should I worry? Perhaps I can even sell mine to the highest bidder when the shite hits the fan.
Hell, maybe the address shortage will create this crazy new "Road Warrior" world where IP addresses are a rare commodity and people have to fight each other with mad overclocked computers just to get some packets routed. And then Mel Gibson can play an ex-help-desk-guy-turned-hero whose Mac was killed by software pirates in the movie version.
All I know is, I'm training my kids how to catch sharp boomerangs.

I'd love to know the zombienet operators' take on the conversion to IPV6.
Lacking <sarcasm> tags,
To make most efficient use of the 4.3 trillion possible IPv4 addresses, all we need is one giant honking DHCP server for the world to use. Of course, the USA should run it forever.

Thats like preventing STDs by amputating your penis. Effective, but there are better solutions available!
I have had 10.x.x.x addresses for a long time and I am gonna keep them. You varmits need to find your own, your not taking away my net addresses. Same goes for the 192.168.X net. That's mine too, it's just my summer home.

Unless my host file grows to be the size of Montana...
Do host files and IPITAV6 work together anyway?
Besides, this is going to make my "There's no place like 127.0.0.1" shirt obsolete in 10 years!
I'll have to get one with colons in it!
Jeeze...

The benefits of IPv6 are numerous, however.
Cisco marketing rep:
NOBODY expects the IPv6!
Our chief benefit is length... greater length of the packet header and and unrememberable addresses...
Our two benefits are greater length of packet header and unrememberable addresses... and rewrite of all network apps....
Our three benefits are length of packet header and unrememberable addresses... and rewrite of all network apps.... and an almost fanatical devotion to some broken standard....
Our four... no...
Amongst our benefits... Amongst our array of benefits... are such elements as greater length of packet header and unrememberable addresses...
I'll come in again.
But seriously, if IPv6 was so good, it would not require so much pushing. If the IPv4 exhaustion was real and imminent, it would not rquire so much pushing.
The moon is not fully subjugated. I demand a second assault wave preceded by a massive nuclear bombardment.
oh great, now we got to worry exploding IPs and routers. People shooting spam at us from every direction. You never know when your gonna step on a 419 and end up buying the "low rate M0RTgaT3".
Maybe we better give control to the UN after all.

>We had an IT person in our london office at a previous job. When I was out there, I had mentioned that they were running out of IP's for the office and we'd have to assign a new block. She pulls out her spreadsheet which is fully poplated up to something like .253, and proceeds to show me all the empty space up to .999.
.255. We should just all follow her lead and go to .999. It's like a network that goes to 11 man.
Obviously we are underutilizing the ipv4 space, no one seems to use anything above

Good point. Imagine the joy:
Cute girl: There's no place like... colon?
You: *sob*
Think maybe I'll pass on that one.
Dewey, what part of this looks like authorities should be involved?
I do IP MASQUERADING. I get only 1 ip address from my provider.
I've got a wireless webcam, a zaurus wireless pda, company assigned laptop, my linux development desktop computer, my Apple G3 running LinuxPPC (my gateway, web, imap server), My oldest son't room with a Linux based AMD 64bit server, a
mini mac, a sharp zaurus, my 2 youngest boys room and thier computer and a laptop up in thier room, my hombrew robot, a hacked compaq IA-1 that runs linux that I use to monitor my firewall, email, etc.. All these devices get to the outside world on 1 ip address. I have multiple servers that are accessed by the outside world via port redirection as well.
That was a lovely story, but you could have just said, "I use NAT and port forwarding."
Also, what's the difference between IP masquerading and IP MASQUERADING? Is the latter more l33t?
