Either they don't exist, or my Google-fu is particularly bad this morning.
I'm trying to get my toes wet with IPv6. I've established an internal
6to4/4to6 tunnel. I'd also like to have a testbed for access to public v6
sites. I'm also trying to find some clue at my upstreams, but figured I'd
ask here as well. Are there any 4to6 gateway available? I have assigned v6
I use this one:
traceroute to 22.214.171.124 (126.96.36.199), 64 hops max, 40 byte packets
1 yttrium.anul.nsa (188.8.131.52) 3 ms 1 ms 1 ms
2 184.108.40.206 (220.127.116.11) 47 ms 46 ms *
3 18.104.22.168 (22.214.171.124) 58 ms 46 ms 45 ms
4 126.96.36.199 (188.8.131.52) 48 ms 51 ms 49 ms
5 tenge2-2.cr3.fra3.content-core.net (184.108.40.206) 47 ms 48 ms 48 ms
6 Tenge2-4-42.cr2.FRA3.content-core.net (220.127.116.11) 49 ms * 70 ms
So my gateway is
inetnum: 18.104.22.168 - 22.214.171.124

descr: Am Tower 5
descr: 90475 Nuernberg
I guess your traceroute goes somewhere else.

Because I'm pedantic, 6to4 and 6in4 are two different things. It sounds like you want 6in4.
They use the same encapsulation, but 6to4 has specific magic in how the outer IPv4 destination is built, taken from the inner IPv6 destination address.
6over4 is different again.
I think someone wrote a draft explaining this a while back.. not sure where or what it was called.

http://en.wikipedia.org/wiki/6in4 = proto-41
http://en.wikipedia.org/wiki/6to4 = proto-41 with 2002::/16 dst
http://fr.wikipedia.org/wiki/6rd = proto-41 with own 6to4 prefix
http://en.wikipedia.org/wiki/6over4 = 6 over 4-multicast (*)
Or for a list which also contains a few others:
* = the only one I really don't get and never saw used
Pedantry is not necessarily a bad thing, especially when the student doesn't
know the right questions to ask.
6in4 is what I was looking for.
