PTR-records map IP addresses to domain names (reverse of A-records).

A PTR-record's name is the IP address written in backward order with "in-addr.arpa." appended to the end. As an example, looking up the domain name for IP address "1.2.3.4" is done through a query for the PTR-record for "4.3.2.1.in-addr.arpa."

You can use the PTR-record in the Raw form only on our servers. The format in which to enter the data is as follows:

Create a zone file name such as: 0.0.127.in-addr.arpa

Raw form:
0    PTR 127-0-0-0.worldwidedns.net.
1    PTR 127-0-0-1.worldwidedns.net.
2    PTR 127-0-0-2.worldwidedns.net.
