[Cialug] DNS Reverse Lookup

[Tom Sellers]

I have set up a DNS server on my home network and although it resolves machine names to IP addresses just fine I can't seem to make it perform the reverse lookup properly.

Below is an example and the DIG information on my DNS server.

Can anyone shed some light on where I have gone wrong here?

tsellers at bluto-laptop:~$ nslookup gw
Server:		192.168.1.9
Address:	192.168.1.9#53

Name:	gw.mydomain.com
Address: 192.168.1.1

tsellers at bluto-laptop:~$ nslookup 192.168.1.1
Server:		192.168.1.9
Address:	192.168.1.9#53

** server can't find 1.1.168.192.in-addr.arpa.: NXDOMAIN

tsellers at bluto-laptop:~$ dig mydomain.com
