[afnog] DNS Problem (PTR Records on different subnets fails)

[Maina M Noah]

Hi Eddy,

i Actually have the zone 0.16.172.in.addr.arpa created in /etc/named.conf

i also have a corresponding zone file created for the above zone in /var/named directory.

However when i run dig -x the (ip address of a host in that zone), no PTR records are indicated.
 e.g  dig -x 172.16.0.2 

i think there is something i am missing.

Hi Maina,

We have reverse DNS working on a server which is in a
different segment than the zones, so it should work.

 e.g.
> 0.2.168.192.in.addr.arpa is zone for 
> existing PTR records and new PTR record is on 172.16.0.0
> subnet which is different ). 

In this case, I would recommend that you add a zone
0.16.172.in.addr.arpa in which you would create the PTR
records for that block.

> created for this? 

So the answer to this is Yes.


Hope this helps,

Cheers,

Eddy
