Quizplus · Accepted Answer

To resolve an IP address to a DNS name, a PTR (Pointer) record is used. The PTR record maps the IP address to a domain name, providing the reverse lookup capability. A records map a host name to an IP address, AAAA records map to IPv6 addresses, and CNAME records map an alias name to a canonical (or primary) name.
