I'm trying to setup reverse DNS for a 6to4 address using the above web site.
IPv4: 220.245.31.42 IPv4 (hex): dc.f5.1f.2a IPv6: 2002:dcf5:1f2a::/48 Reverse: a.2.f.1.5.f.c.d.2.0.0.2.ip6.arpa
Above is the web site's details about my system. Before anyone mentions it I know it's common practice to obscure details of addresses before posting to lists, but I'm not publishing anything that couldn't be discovered by reading headers of mail sent out from my system.
Name server 1: ns.sws.net.au.______ Error Either you have entered an invalid nameserver description or the nameserver you refer to has no zone for this reverse delegation.
When I try to submit the form I get the above errors from all of my DNS servers.
It must be a decade since I used this service last, and it looks exactly the same! All your config looks fine. I did a few nslookups against your servers for your ip6 zone and everything came up as expected. So you've done all the sensible things, so maybe a few silly suggestions might be appropriate... have you tried without the trailing '.' at the end of the nameserver name? Have you tried an IP address? It would be nice if it differentiated between "I don't like the name of the nameserver you have specified" and "there is something wrong with your dns records" (or more usefully - "this is wrong with your dns records") James
