Reverse dns not work
« on: March 01, 2008, 09:32:22 AM »

I'm from Bulgaria, so please excuse my english :) I have 1 c class net and deside to use ipv6 from tunnelbroker. Everything is ok but the reverse dns doesnt work for me. I use my own name servers. They work fine :
(root@mail)-(07:29pm)-(03/01)-(3)
(~)> host -6 test6.web-bg.org
test6.web-bg.org has IPv6 address 2001:470:9009::1
(root@mail)-(07:29pm)-(03/01)-(3)
(~)> host -6 2001:470:9009::1
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.9.0.0.9.0.7.4.0.1.0.0.2.ip6.arpa domain name pointer test6.web-bg.org.

But other name servers doesnt find my reverse hosts. In my account I put my dns servers, and wait about 48 hours but nothing.. What is work?

Regards Nikolay

It looks like you're using the new /48 allocation, and rdns is not yet functional for that, as I understand it.
(Correct me if/where I'm wrong)
Hope this helps.

rDNS for /48s isn't fully operational yet, which is why it isn't working.
I'll update the News section once it and some other updates are in place.

Ok, now I'm using /64 but the same story. Admin can u help me. My name server works fine and resolv the right host but other name servers didn't resolv.
root@laptop:~# nslookup 2001:470:1f0a:2bb::2
Server:         83.222.183.2
Address:        83.222.183.2#53

ns1.ipv6.he.net internet address = 64.71.188.2
ns2.ipv6.he.net internet address = 64.71.189.2

root@laptop:~# nslookup 2001:470:1f0a:2bb::2 ns.joni-b.net

It is because you aren't allowed to change the rDNS for your tunnel's /64, only your routed /64:

tunnel's: 2001:0470:1f0a:2bb::/64

Routed: 2001:0470:1f0b:2bb::/64

Note the difference, 1f0a vs. 1f0b
