Me again with more IPv6 stuff. I contacted my domain registrar, Namecheap, to add IPv6 glue records to my domain so that I could fully set up IPv6 AAAA DNS records. They said the records were added, and I configured BIND accordingly, but there seems to be a hitch somewhere along the way. What do I mean? See for yourself. From one of your IPv6-enabled servers (you do have one, right?), ping6 (or anything that will look up and return the IPv6 address associated with) ns1.dstrout.net AND ns2.dstrout.net. Chances are, one of them will work but not the other. It seems to be the case with all my IPv6 servers, as well as various other IPv6 ping services online.
So, any idea why? I've mentioned the problem to Namecheap, but they'll undoubtedly have to check with eNom, their upstream provider (which they had to do to set the records in the first place), so I was hoping someone here could help me. I suppose it's not really that big a deal, any computer doing an IPv6 lookup should fail over to whichever nameserver it can reach, but I want this to work properly.
