They are beta testing general deployment options for v6. I asked if they had a timeline for general deployment, but they did not have anything at this time.
I myself work for a registrar (corporate, not retail) and we can do ip6.arpa via slaving and AAAAs as well, but our frontend UI still has yet to support AAAA at all...
Well, good luck with sage. I'm not sure if dyndns.org supports v6 glue records. Although you could add another NS out of baliwick which has a AAAA glue record and I think
the test will pass.
EDIT: oh never mind, I saw u passed. I guess they do support IPv6 glue (just did a dig and saw that they do).
Also, the daily tests are kind of picky, so be careful with your script. Can't use the same IPv6 server twice, and sometimes the script refuses to parse whois and ping output correctly for no apparent reason.
