Reverse IP Lookup
About Reverse IP Lookup
Reverse IP Lookup will list PTR records for IP address, PTR records are used for the Reverse DNS (Domain Name System) lookup. Using the IP address you can get the associated domain/hostname. An A record should exist for every PTR record.
While in the domain DNS zone the hostname is pointed to an IP address, using the reverse zone allows to point an IP address to a hostname.
In the Reverse DNS zone, you need to use a PTR Record. The PTR Record resolves the IP address to a domain/hostname.
