What is pointer (PTR) record?

A pointer PTR record is a resource record in a zone file that contains a record associating an IP address with a host name in the in-addr.arpa domain. Pointer (PTR) records are used for reverse name lookups and provide host name to IP address mappings. Here is an example of a PTR record:      IN  PTR     server9.microsoft.com.

In this PTR record, the IP address is mapped to the host Server9 within the microsoft.com domain. Note that the IP address of the host appears in the reverse order in the in-addr.arpa domain.
