/48 rDNS delegation works, /64 rDNS doesn't
« on: January 03, 2012, 05:55:35 AM »
I have the networks 2001:470:19:a87::/64 and 2001:470:fab7::/48. When I am testing my rDNS, I found that the /48 delegation works but the /64 delegation doesn't. Here are the full dig output:

Re: /48 rDNS delegation works, /64 rDNS doesn't

The query is getting to the HE.NET nameservers, but they apparently don't have a delegation set up for your /64.
About all you can do is to verify the setup on the tunnelbroker page (verify the RDNS delegation), then send an e-mail to ipv6@he.net so they can investigate.
