It's a french one.. There's really only Orange/Wanadoo there (all the large businesses in france are state owned, so you don't get a lot of competition), which narrows it down somewhat:p
No mention outside slashdot of *any* ISP doing this though that I can find.. google let me down.
Of course explaining how to get all the linksys/dlink/etc. routers that their customers have to act as RA servers.. that's hard. I don't envy the ISP that need to do it.
Cisco 'supports' it provided you upgrade IOS and have the right contract, and anyone who's ever run that knows you never upgrade it short of someone putting a gun to your head - too much stuff breaks.
Looking around me I see a VOIP phone (ipv4 only), printer (ipv4 only), wireless router (ipv4 only), server (HP, ipv4 only, support contract does not allow OS reconfiguration), the cisco router which actually does ipv6 and this laptop.
So I could enable ipv6 between two devices. Except the leased line doesn't support it incoming because there's no ipv6 capable hardware at the other end... so there's little point.
Total cost to upgrade just this small office would be my hardware budget for about 5 years... and just is *not* going to happen.
Vista's Teredo only works behind certain types of NAT. It works at home behind the cisco - but then it's already on an ipv6 capable network (and you have to manually switch teredo off in that case.. a complete pain in the ass that should happen automaticaly).
Try it behind a corporate firewall and you're hosed... never seen it work here for example.
Those using NAT as an automatic firewall are generally using commodity routers which don't support ipv6 anyway.
For the ISP to be a able to distribute ipv6 to multiple machines in they way you imply you'd need something forwarding the RA requests to them.. normally you don't do that - you get a/64 and use your own router to allocate addresses within the local LAN (plus dhcpv6 to handle all the other configuration information).
If they're using their own routers I guess they could do it.
Security isn't the issue - you just have a router that blocks inbound traffic just like before.
You dont need to "switch" per se, you can use v4 and v6 at the same time easily.
In which case why bother? You don't need two protocols to connect.. only one.
You *do* need ipv4 because a lot of applications, services, even websites are strictly ipv4 only - and for bespoke applications probably always will be.
There are no ipv6 only applications, services or websites. So you're just spending money for zero benefit.
Show a sound business case for adoption of ipv6 and you'll get adoption. Until that happens you won't.
Part of the national healthcare budget goes on educating the population so that you don't have 75% obesity.. when you have a system designed so that it's in the interests of the medical profession that the population is unhealthy (as they pay more money) then that's what you get.
- Upgrading an IPv4 CISCO network device, such as router, gateway or firewall, is this: 100% software, hardware upgrade and are does CISCO charge you for the pleasure:
Well it depends on the device.. you'd need a recent IOS if your image doesn't support it.
Presumably you have a support contract on the device so you can download it directly.. of course there's the whole QA, Testing thing you have to do before deployment. It's not a 5 minute job.
Ciscos ipv6 firewall is actually quite passable, but you can only configure it by the command line.. no SDM weenies allowed:p
Well, what if somebody told you that if you didn't start doing that there'd eventually be no coffee for anybody?
I'd tell them that firsly a few rich people had hoarded all the coffee and they needed to give it back, and everyone else can just share cups until that happens. Oh and in the worst case the coffee isn't going to run out for 10 years plus anyway.
Desktops are only the start. Your servers need it (no ipv6 AD support). No ipv6 network printer support. No ipv6 VOIP support. Poor to nonexistant ipv6 router support, and of those that do most of them don't support firewalling it. Poor to nonexistant connectivity. Try asking the average ISP for an ipv6 address and they'll just look at you funny. It's not just consumer ISPs either - this business park I'm in at the moment has *no idea* what ipv6 is and has no timescale to look at it either.
Then there's the bits and pieces.. Dies Blackberry support ipv6? I know iphone doesn't, and Symbian's implementation is broken (relies on a dhcpv6 server and even then seems to need some kind of proprietary extension to that).
The problem with that site is it's counting down... in the last few years more address space has been released than claimed, so it should be static or counting up.
ipv6 has been needed 'real soon now' for 20 years. Yes we'll need it eventually, but it's so far from commercial deployment that it's just not an option - most infrastructure simply doesn't support it (in fact trying to run ipv6 over active directory will utterly screw it up because of the conflict between xp supporting ipv6 ad clients and 2003 not supporting them.. everything runs horrendously slow or breaks).
It wouldn't surprise me at all if adobe didn't do a binary for iphone like they did for symbian - it's in their interest for it to be available for as many platforms as possible (they make the money on the encoding.. the flash developer stuff costs many many $$$).
You need a fairly beefy PC to decode that and a lot of non-geeks just don't have that kind of power - and the BBC want the format to be readable on as many (UK based) PC's as they can.
How much of that data could be traced back to you anyway? Unless they're sending email and postal address..? They can't really avoid sending the IP address (short of bouncing the results through Tor or something) but may not actually store it at the other end (for example we make a point of never storing IPs, only country information) but installation statistics are useless on an individual basis - they simply indicate patterns when combined with the statistics of other users.
If they want to sell that information (and nothing so far has said or implied that they do) then it's only usage information for a single product.. it's not the kind of stuff that goes for bug bucks.
You can very easily script IOS, just use the copy command to copy a file onto the running confog. This is basic IOS that you should have learned in school.
Slashdot Mirror
Interesting.. the last CCNA I look at didn't even mention it (about 3-4 years ago).
:p
Now if they would just allow support for it in SDM... editing the firewall with vi is fine but it's nicer with a little gui
They made a deadline for the capability not the adopton.
Upgrade the router firmware to make it possible.
Install ipv6 on XP/2000 desktops.
There, you're capable. You're not actually *using* it, probably because half your apps don't work with it anyway... that can take as long as you like.

You want to send a guy dressed as an elephant do your boss??
Anyway I digress... jumbo frames have been supported on ipv4 for years.

iPhones and iPod Touches have v6 enabled by default
No they don't - apple ripped the ipv6 support out when they ported osx to them.

Not really. It does nothing else that can't be done on ipv4 for a lot less and without spending billions on hardware upgrades.

ipv6 NAT exists. Cisco routers support it.

Anyone notice that the volume control goes up to 11?
:p
That's for watching TV really loud
I wasn't about to install kontiki based software on any of my machines, even the ones with Windows on them.
Flash will suit me fine. Almost every device I have can play it in some form (except the iphone, but hopefully that's coming one day).
It installed a device driver. Once that's done no OS prevention or design would stop them doing what they wanted.
The same would happen in Linux if they had a CDROM and some idiot forgot to mount the drive containing the install binary nosuid.

It is a closely guarded secret.
Clearly not *that* closely guarded..
The newer linksys boxes do *not* use Linux, only the ones they inherited when they bought the company.
I can't see cisco policy changing.. they'll use a proper embedded OS or simply open IOS to certain plugins without changing the OS at all.
