Pointer (PTR) Pointer (PTR) record. Points to a location in the domain name space. PTR records are typically used in special domains to perform reverse lookups of address-to-name mappings. Each record provides simple data that points to some other location in the domain name space (usually a forward lookup zone). Where PTR records are used, no additional section processing is implied or caused by their presence. (RFC 1035)
