RE: [cobalt-users] reverse lookups

["Patrick McNeil" <pmcneil@xxxxxxxxxxxxx>]

Couple of thoughts.

-first you are using the .0 address. Correct me if I am wrong but isn't this
the network address for the 195.149.33.X network. This would mean that you
don't want to use that address. Seems to work though. Just another thought

-Using your name server I was able to do a reverse lookup on the IP. But
using other name servers it didn't work.

-This means you are not authoritative for the IP's. This works much the same
was as domains work. In order for the world to see your dns entries for your
domain name you have to be registered and listed as authoritative for the
domain. So it is with IP's. Who ever provides you with IP's (appears to be
RIPE Network Coordination Centre) is currently the authority for your IP's.
Basically they need to configure their DNS servers to either point PTR
request for your IP's to your server, or make their server a secondary name
server for the zone 0.33.149.195.in-addr.arpa which would be the zone for
the 195.149.33.x block of addresses.

Your problem is that reverse lookups currently go to the DNS servers for the
RIPE Network people. Their server doesn't appear to be setup at all to
handle this. Your server is never even asked for the record by anyone not
directly using your server for DNS.

I hope this makes sense. Ask more questions if needed.

can anyone out there help me with this one?

iv added my domain and followed the cobalt DNS quick guide step by step (it
is straight forward)
i ticked the box for reverse lookups and have the domain on its own IP
i can do: NSLOOKUP DOGSQUAD.CO.UK and it resolves to 195.149.33.0  but i
cant do a NSLOOKUP 195.149.33.0 and resolve it to DOGSQUAD.CO.UK


any ideas why i cant do a reverse lookup on this domain?
