First steps towards v6 support by ATT?
While researching at&t and ipv6 I came across http://www.feise.com/~jfeise/blogs/index.php?blog=8 and also http://www.corp.att.com/gov/solution/network_services/data_nw/ipv6/ Looks like they have established a tunnel in the United States perhaps? I realize that getting native v6 support to DSL users isn't exactly a high priority for US IPSes, but building tunnel servers that are on the same continent as the user base is nice. :) .... of course that tunnel might be broken. Can anyone comment on this?

doesn't that blog basically say: "it's broke Jim..." and that 7018 (really 7132) passes off the anycast into HE.net?

how did you gather that? Maybe Tom knows more about this and can let us all know? -Chris

Yes. It does say it's broken. However it's entirely possible that AT&T hands out different routes to their l33t enterprise/govt customers with t1 or better who pay real money, vs end users.

From: Remote Access Service to IPv6 Internet * Support IPv6 for small (or satellite) locations and individual remote users * Reach a dynamically configurable IPv6 Tunnel Gateway through IPv4 ISPs through fractional T1, DSL or dial-up access * The Tunnel Setup Protocol (TSP) will be used to create tunnels to transport IPv6 traffic over an IPv4 network to the gateway Granted that doesn't necessarily mean it's in the United States, but I'm guessing it would be due to being an offering targeted at the United States Government. :) Hence my request for more comments/information. Maybe off topic for NANOG but then what does that even mean anymore? :)

yea... maybe they do, I don't see that from my view of 7018's routing data (limited as it may be)

wow, 'tsp'... uhm, what's that I wonder? This: http://www.broker.ipv6.ac.uk/download.html perhaps?? yeek!

Sure... I'd love to know though :)
Hence my request for more comments/information.
agreed

I'm fairly sure that operating a network (even a v6 network) is on-topic for nanog.

Interesting.

Yes looks like. Especially with the mention of DSL/dial up access. Plus I seem to recall some discussion around the ipv6 mandate having some language specifying they had to support it transit wise, but not necessarily be on v6 addresses. [1] Anyone from .gov with ATT connectivity care to comment (both on the nature of the native/tunneled v6 offering and the actual requirements of meeting the mandate) [1] Language from http://georgewbush-whitehouse.archives.gov/omb/memoranda/fy2005/m05-22.pdf "Meaning the network backbone is either operating a dual stack network core or it is operating in a pure IPv6 mode, i.e., IPv6-compliant and configured to carry operational IPv6 traffic."

so, actually, looking at 7018's route-server: route-server> sho ip bgp 192.88.99.1 | in recei 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) 7018 1239, (received & used) seems they prefer Sprint for 6to4 services... 7132 doesn't have a publicly listed route-server :( oh well. -chris
