DNS reverse lookps - what is this for?

[1665]

Hi, in our DNS setup we have forward look ups to convertnames to IP addresses, but what is the reverse lookup for and do I need it?

1665, reverse lookups are almost as important as the ones that you mention (widely known as forward lookups). Many applications rely on reverse lookups to figure out the name behind a given IP. If you are setting up your DNS manually then this tasks of creating the reverse lookup db files will become tedious as your domain grows. If on the contrary you are using a DNS GUI or similar it should be creating them automatically. You can check this with your DNS vendor.

Thanks for your reply, can you explain how I can automate this, at the moment I have nothing in the reverse lookup folder in DNS......

Kind regards

If you run your DHCP on 2000, you can tell it to register clients in reverse zone, on behalf of the client.

Im not 100% if this feature works when DC's are NT4
