What are RP Records?
RP Record specifies the mailbox of the person responsible for a host (domain name). The RP Record type makes it possible to identify the responsible person for individual host names contained within the zone. Optionally specify the domain name for a TXT Record with additional information (such as phone and address). The RP Record type is defined in RFC1183.
