Just for the record -- worked with GoDaddy over the last few weeks to find out why I can't get DS keys added to a zone, onlyv6.com. Their DS-adding interface (selective and bulk) errors out.
It culminated today with lots of back and forth with the front-line support (that interfaces, via chat, with the Advanced Technical Support team). After some red herrings about lack of connected to our nameservers (I had to send screenshots that I could ping all three nameservers), a concern that a nameserver didn't have a matching PTR record, and that not all nameservers were at the same serial number (one was at a slightly older one), it came down to that they require two working IPv4-enabled nameservers in order to add a DS key. Having an IPv6-only zone is apparently not acceptable. Kudos to the two front-line support reps that were professional and did their level best (though one remarked he had never seen an IP address like that before). I suspect that GoDaddy's backend DS validation system has some kind of bug that prevents contact with an IPv6-only zone. Anyone know of a registrar that supports both IPv6 and DNSsec? Frank
