NS3.HE.NET is behaving weirdly
« on: December 18, 2009, 07:06:33 PM »

I have a tunnel account at Hurricane Electric and I've setup rDNS delegation for my prefix (2001:470:f803::/48).

As you can see above, when NS3.HE.NET is queried, it returned NS record as
'\032\009\032\032\009\032\032\032abbe-v6-router1.pirateparty.in.', causing
rDNS to break 10% of time.

should be emailing in a trouble ticket to ipv6@he.net for these sorts of things.

edit 1 - you had lots of whitespace before your second nameserver entry to delegate to, removed it, pushed out rdns again, waiting to see if that clears it up.

edit 2 - didn't seem to clear it up yet, poked DNS maintainer, waiting to hear back.

edit 3 - please retest, changes appear to have propagated.

Sorry, I didn't realize that. Mailed to ipv6@he.net.
