The PTR record is a very popular DNS record and is also commonly known as the Pointer record. Its purpose is to map an IP address to the domain name that corresponds to it. It serves exactly the opposite function of the A record, which directs the domain name to its IP address (IPv4). The Pointer record is commonly used in Reverse DNS lookups, a query that starts with the IP address and looks up the domain name. Learn more information about the PTR record!
