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 :
(~)> host -6 test6.web-bg.org
test6.web-bg.org has IPv6 address 2001:470:9009::1
(~)> host -6 2001:470:9009::1 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.


Thanks, I build new tunnel with /64 and I'll wait to see is the reverse dns works.


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

Non-authoritative answer:        name = friend-pt.tunnel.tserv6.fra1.ipv6.he.net.

Authoritative answers can be found from:        nameserver = ns1.ipv6.he.net.        nameserver = ns2.ipv6.he.net.
ns1.ipv6.he.net internet address =
ns2.ipv6.he.net internet address =

root@laptop:~# nslookup 2001:470:1f0a:2bb::2 ns.joni-b.net
Server:         ns.joni-b.net
Address:        name = test6-2.web-bg.org.

What is wrong now ? Thanks


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


Thanks again, It was my mistake  ;D You may close the topic  ::)
