I had some freetime this afternoon, so I whipped up a script to check IPv6 deployment at the Big Ten. I checked for AAAA records for authoritative nameservers and SMTP servers.
Only University of Illinois, Urbana-Champagne and Penn State had any IPv6 presence. We both have one IPv6-accessible authoritative nameserver.
Yes, otc2.psu.edu is IPv6-accessible. It's answering DNS and NTP queries over IPv6. At the moment, it's not answering recursive queries over IPv6, but TNS is aware of this issue and hopes to have it corrected soon.
So, hats off to TNS for this. It's good to be ahead of the pack.
