How do you setup reverse DNS?
Posted by Darren Radsmith on 04 June 2004 10:50 PM

Within DNS Made Easy, configuring reverse DNS domains and PTR records is quite easy. The very much larger issue will be getting the owners of these IP addresses to delegate reverse DNS for the netblock(s) assigned to you to the DNS Made Easy name servers.

Reverse DNS is the responsibility of the owner of the IP addresses (i.e. the organization allocated the IP addresses from an RIR). If you have a sizable netblock assigned to you from a provider, then they will usually (but not always) delegate reverse DNS for those addresses to external name servers. If you only have a few (or one) IP address assigned to you from a provider, then it is often easiest to simply request that provider set the reverse DNS entry for the IP addresses assigned to you to the value that you require.

If you would like to have the reverse DNS delegated to DNS Made Easy so you can administer it within our control panel, you need to set up a reverse DNS domain. This is a special domain that ends with "in-addr.arpa". This domain is created in DNS Made Easy in the same manner as any other domain. You will need to ask your provider what reverse DNS domain to make once they have performed the delegation to DNS Made Easy name servers. After creating the "in-addr.arpa." domain in the DNS Made Easy control panel, PTR records are defined within it.
