Locating Session Initiation Protocol Servers in a Dual-Stack IP Network
RFC 7984, “Locating Session Initiation Protocol Servers in a Dual-Stack IP Network”, is a Proposed Standard document published in September 2016 by O. Johansson, G. Salgueiro, V. Gurbani, D. Worley. It updates RFC 3263. The canonical text is published by the RFC Editor.
Abstract
RFC 3263 defines how a Session Initiation Protocol (SIP) implementation, given a SIP Uniform Resource Identifier (URI), should locate the next-hop SIP server using Domain Name System (DNS) procedures. As SIP networks increasingly transition from IPv4-only to dual-stack, a quality user experience must be ensured for dual- stack SIP implementations. This document updates the DNS procedures described in RFC 3263 for dual-stack SIP implementations in preparation for forthcoming specifications for applying "Happy Eyeballs" principles to SIP.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
