The IESG has approved the following document: - 'On Interoperation of Labels Among Conventional DNS and Other Resolution Systems' (draft-ietf-dnssd-mdns-dns-interop-04.txt) as Informational RFC This document is the product of the Extensions for Scalable DNS Service Discovery Working Group. The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dnssd-mdns-dns-interop/ Technical Summary Despite its name, DNS-Based Service Discovery can use naming systems other than the Domain Name System when looking for services. Moreover, when it uses the DNS, DNS-Based Service Discovery uses the full capability of DNS, rather than using a subset of available octets. In order for DNS-SD to be used effectively in environments where multiple different name systems and conventions for their operation are in use, it is important to attend to differences in the underlying technology and operational environment. This memo presents an outline of the requirements for selection of labels for conventional DNS and other resolution systems when they are expected to interoperate in this manner. Working Group Summary Early in the life of the draft there was extensive discussion (with a very few people supplying most of the bits) on clarifying the scope of the draft and sometimes-diverging terminology, since DNS operators and implementers think of interoperability issues between name resolution protocols differently than operators and implementers of mDNS or other such protocols. Those confusions appear to have been resolved in the final draft. The primary difference between the individual -00 version and the current one is extensive explanatory text on the nature of the problem being addressed and some of those divergent uses of terminology. Document Quality This document is intended as advice to implementers, to promote interoperability among multiple protocols. Review in DNSOP was requested, as it discusses operational conventions about the public DNS. Personnel Shepherd: Suzanne Woolf AD: Terry Manderson
