A Reverse Lookup Zone is a DNS zone that contains the records of mapping IP addresses to their network resource names. PTR record is also known as a Pointer Record and it exists in the Reverse lookup zone. PTR record provides the Hostname associated with an IP address. PTR record is exactly the opposite of the A record, which provides the IP address associated with a Hostname.
