[Pdns-users] PDNS reverse lookup's

[Philip Urwin]

this is a dig to the external ip address which doesn't resolve the domain name
@DNS:~$ dig @192.168.1.10 -x 173.194.41.133

; <<>> DiG 9.8.1-P1 <<>> @192.168.1.10 -x 173.194.41.133
; (1 server found)

but a dig to the loopback address comes up with 
@DNS:~$ dig @127.0.0.1 -x 173.194.41.133

; <<>> DiG 9.8.1-P1 <<>> @127.0.0.1 -x 173.194.41.133

this is what I would expect from a dig command to an ip address which suggests that the problem lays in the transition between the recursive and the authoritative sides of th server

Can you put your configurations somewhere? Can you try

dig -x 173.194.41.133 @loccalhost
