sprint.net has a pretty nice one. Theirs isn't an IPv6 day exclusive either. Kind of amusing address for a telecom company...

For anyone else whose ISP doesn't support IPv6:

  PING sprint.net: 56 data bytes
  64 bytes from www.sprint.net (2600::): icmp_seq=0. time=156. ms
  64 bytes from www.sprint.net (2600::): icmp_seq=1. time=151. ms
  64 bytes from www.sprint.net (2600::): icmp_seq=2. time=153. ms
  64 bytes from www.sprint.net (2600::): icmp_seq=3. time=151. ms
  64 bytes from www.sprint.net (2600::): icmp_seq=4. time=151. ms
  
  ----sprint.net PING Statistics----
  5 packets transmitted, 5 packets received, 0% packet loss
  round-trip (ms)  min/avg/max/stddev = 151./152./156./2.5

2600 refers to https://secure.wikimedia.org/wikipedia/en/wiki/2600 (first two articles on the disambiguation page are relevant).

This is kind of nice pun indeed, thanks!

I use dead:beef and feed:cafe for my 2 small subnets on a /48 I got from he.net, because it's easy to remember.

Of course, if you really want to identify your allocation, setup reverse dns. To do it the easy way go to afraid.org. They offer a great free service, IMHO better than dyndns.

HE also offer a free DNS service now, considering you've already made an account with them.

Also: their DNS recursive server is whitelisted by google, so you can get YouTube videos over IPv6

I'm already using it, 2001:470:20::2 or 74.82.42.42, but I didn't know they did reverse DNS as well.

I'll think about it. For now afraid.org just works.
