Network Service Access Point (NSAP) address record. Maps a DNS domain name to a single NSAP address of any supported format or type. NSAP mapping records are typically used to assist in managing connection for existing portions of the global Internet that currently deploy OSI low-layer protocols, comprising the Connectionless Network Protocol (CLNP) and its supporting routing protocols.
