really simple dns question

[apocalypse11]

in cmd prompt nslookup - mycomputer and it returns ip x.x.x.x

nslookup x.x.x.x returns notmycomputer?

where do i need to go to change this and how is it done once i get there.

can anyone point me to some simple instructions or help...

Thanks...

You need to create a reverse lookup zone for x.x.x.0
