www.sprint.net has IPv6 address 2600::

Windows 2000 had an experimental v6 stack. Windows XP has IPv6, but you need to type "ipv6 install" at the command line to enable it.

Sure it has, since Vista.

Or on XP you can type "ipv6 install" on the command line to enable it.

Since when does a user have to type the http:/// in a browser bar?

That's a hostname (which is already supported via IDN, such as http://xn--malmpeeps-37a.se/ ), this story is talking about TLDs.

There's no technical reason Mönsterås can't have mönsterås.se

You're not allowed to re-sell IP space.

IPv6 is lighter weight than NAT. NAT requires connection tracking, for one.

In many ways IPv6 is lighter than IPv4, because router fragmentation and several disused packet options are not allowed.

At current rates, a class B (/16) lasts about 2.5 hours. A class A (/8) lasts about a month.

Not really worth the hassle when we can just start using IPv6.

Except that you're not allowed to re-sell IP addresses, they are owned by the IETF.

One reason Comcast is so pro-ipv6 is that they've run out of 10.0.0.0/8 to privately number the cable modems of their subscribers, and have had to get ARIN allocations to keep signing new customers up.

Both of my routers support IPv6 (wrt54g and airport express), maybe I'm just lucky.

Get a copy of Working Effectively With Legacy Code. It'll help you get tests around the code base that give you the confidence to be able to change it without breaking anything.

Comcast will give out /64s from what I recall. That's the smallest allowed network size for most IPv6 tools (radvd etc).

That leaves 2**64 addresses for your home network, or just let your hosts auto-create their local address which is the default config.

Network size on IPv6 is /64, not /96. Companies are usually given a /48, and ISPs a /32.

If your ISP tried to restrict you to ::1 for some reason, you could tunnel out to a broker that gives you a /64 or /48. I can't see why anyone would, Comcast for example has no plans to.

I was going to make a similar joke.

No coincidence that I'm halfway through Fowler's book at the moment.
