Network Working Group B. Manning Request for Comments: 1637 Rice University Obsoletes: 1348 R. Colella Category: Experimental NIST June 1994 DNS NSAP Resource Records Status of this Memo This memo defines an Experimental Protocol for the Internet community. This memo does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited. Abstract The Internet is moving towards the deployment of an OSI lower layers infrastructure. This infrastructure comprises the connectionless network protocol (CLNP) and supporting routing protocols. Also required as part of this infrastructure is support in the Domain Name System (DNS) for mapping between names and NSAP addresses. This document defines the format of one new Resource Record (RR) for the DNS for domain name-to-NSAP mapping. The RR may be used with any NSAP address format. This document supercedes RFC 1348. NSAP-to-name translation is accomplished through use of the PTR RR (see STD 13, RFC 1035 for a description of the PTR RR). This paper describes how PTR RRs are used to support this translation.
