PTR (Pointer) records resolve IP addresses to domains. They map a network interface (IP) to a hostname for a Reverse DNS configuration. PTR records are configured within Reverse DNS domains.
PTR records work similarly to A records, but rather than providing the domain name’s associated IP address during a lookup, it provides the domains when an IP address is used as the search method.
Common Use Cases for PTR Records
PTR records are used in reverse DNS lookups to find out what IP address is associated with a particular domain or hostname.
