Ticket ID: SIXXS #2096965 Ticket Status: Resolved PoP:
Reverse DNS delegation not operational
![[us]](/s/countries/us.gif) Shadow Hawkins on Saturday, 19 June 2010 00:53:36
I setup my subnet recently, and set the reverse DNS delegation, but when I try to do a reverse lookup, the DNS servers are not delegating to my zone on the other server.
Details:
Subnet: 2001:1938:270::/48
Reverse DNS Delegation to: ns1.afraid.org., ns2.afraid.org., ns3.afraid.org., ns4.afraid.org.
doing a "dig -x 2001:1938:270::2" returns:
;; QUESTION SECTION:

If I'm reading this right, the TTL on the reverse zone above my subnet is one *week*. I would have thought that adding the reverse DNS delegations would have updated the zone (including serial number, which indicates that it is last updated on June 13th using standard serial number sequencing), but it seems it has not.
Will this rectify itself in a week, or is this a case of a missed serial number update on said zone, or some other issue?
Thanks.

Seems bind didn't want to reload new zones any more for whatever reason it had. All should be fine now.

I suspect that I'm having the same problem that Gavin was experiencing.
I'm in the same POP has he, usphx01, and I'm seeing similar results. Perhaps, I'm not as confident that my DNS resource records are correctly formed.
Locally I can resolve:
# dig -x 2001:1938:243::30

;; AUTHORITY SECTION:
3.4.2.0.8.3.9.1.1.0.0.2.ip6.arpa. 86400 IN NS ns1.buici.com.
From another machine on the network, I am not seeing the expected delegation.
# dig -x 2001:1938:243::30

The serial number of the zone implies that it hasn't been updated since the 17th. I configured my rDNS delegation on the 19th.
The delegation setup page states:
"Do note that changes are not applied directly, as such, after a change wait a bit before checking."
How long should we need to wait?
Cheers

Found the problem, should now be definitely resolved, thanks for reporting.
Zones should update every 15 minutes now.
