IPv6 (or, hello from 2001:470:1f04:900::2 !)

I figured it was time to learn IPv6 so I setup IPv6 at home using Hurricane Electric's free tunnel broker, one termination point of which is across the Bay in Fremont, so latency overhead is negligible, and he.net's IPv6 deployment is good (or so Lorenzo tells me).
sammy:~# ping6 ipv6.google.com
PING ipv6.google.com(2001:4860:0:2001::68) 56 data bytes
64 bytes from 2001:4860:0:2001::68: icmp_seq=1 ttl=58 time=97.7 ms
64 bytes from 2001:4860:0:2001::68: icmp_seq=2 ttl=58 time=96.9 ms
64 bytes from 2001:4860:0:2001::68: icmp_seq=3 ttl=58 time=97.2 ms

(Not that much worse.)

And I can now see all the dancing logos on various websites. (it's IPv6 tradition to serve animated GIFs of your company/site logo for people accessing it over IPv6.... silly, but cute.)

Still have some work to do... I need to get the rest of my machines routing through my Linux server (the one with the tunnel), including wifi. What's the typical configuration here? DHCPv6 and broadcast the route? Or does the IPv6 stateless auto-configuration for assigning the locally-scoped/link-local/etc addresses also include smarts of hosts w/ gateways advertising that?

In any case, still clueless, but at least with the tools to get slightly less clueless now.

It's weird having my own /64. (that's 2^64 addresses for my house)
