This format may be used with the any + proposal that has variable length addresses, but is targeted for CLNP + use. + + This memo assumes that the reader is familiar with the DNS [3,4]. + +Background + + This section describes an experimental representation of NSAP + addresses in the DNS. There are several reasons to take this approch. + First, it provides simple documentation of the correct addresses to + use in static configurations of CLNP compliant hosts and routers. + + NSAP support requires that a new DNS resource record entry type + ("NSAP") be defined, to store longer Internet (i.e., NSAP) addresses. + This resource record allows mapping from DNS names to NSAP addresses, + and will contain entries for systems which are able to run Internet + applications, over TCP or UDP, over CLNP. + + + + +Manning [Page 1] + +RFC 1348 DNS NSAP RRs July 1992 + + + The backward translation (from NSAP address to DNS name) is + facilitated by definition of an associated resource record. This + resource record is known as "NSAP-PTR", and is used in a manner + analogous to the existing "in-addr.arpa". + + These RRs are intended for use in a proposal [6] by one of the + members of the NOOP WG to address the next-generation internet. + +The NSAP RR + + The NSAP RR is defined with mnemonic NSAP and type code 22 (decimal). + + An NSAP (Network Service Access Protocol) number is a unique string + to OSI transport service. + + The numbering plan follows RFC 1237 and associated OSI definitions + for NSAP format. + + NSAP has the following format: + + <owner> <ttl> <class> NSAP <length> <NSAP-address> + + All fields are required. + + <length> identifies the number of octets in the <NSAP-address> as + defined by the various national and international authorities. + + <NSAP-address> enumerates the actual octet values assigned by the + assigning authority. Its format in master files is a <character- + string> syntactically identical to that used in TXT and HINFO. + + The format of NSAP is class insensitive. NSAP RR causes no + additional section processing. + + For example: + +foo.bar.com.
