Reverse lookup zone in dns is not updating

Archived from groups: microsoft.public.win2000(More info? )I have a Standard Primary Forward Lookup zone and a Standard Secondary Forward Lookup zone on another server.Both are set to allow zone transfers between the two.However, while my Reverse zone transfers fine, my Forward zones do not transfer at all.I am unable to add records to the secondary and I cannot get the host records from my primary to transfer. Reverse DNS is IP address to domain name mapping - the opposite of forward (normal) DNS which maps domain names to IP addresses.Reverse DNS is maintained in a separate set of data from forward DNS.For example, forward DNS for "" pointing to IP address "", does not necessarily mean that reverse DNS for IP "" points to "".

However there is one important exception: Many e-mail servers on the Internet (including AOL's) are configured to reject incoming e-mails from any IP address which does not have reverse DNS.So if you run your own e-mail server, reverse DNS must exist for the IP address that outgoing e-mail is sent from.In most cases it does not matter what the reverse DNS record for your IP address points to as long as it is there.If you host multiple domains on one e-mail server, just setup a single reverse DNS record to point to whichever domain name you consider primary.

(e-mail servers checking for reverse DNS know that it is normal to host many domains on a single IP address and it would be impossible to list all those domains in reverse DNS for the IP).

A special PTR-record type is used to store reverse DNS entries.
