The IESG has approved the following document: - 'Locating Session Initiation Protocol (SIP) Servers in a Dual-Stack IP Network' (draft-ietf-sipcore-dns-dual-stack-08.txt) as Proposed Standard This document is the product of the Session Initiation Protocol Core Working Group. The IESG contact persons are Alexey Melnikov, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-sipcore-dns-dual-stack/ Technical Summary This document lays the groundwork for future "Happy Eyeballs"-style work on SIP by updating DNS procedures for SIP URI resolution rules in a way that clarifies behavior for SIP stacks that support both IPv4 and IPv6. Working Group Summary The document spent several years in the working group, with occasional bursts of activity. The final push to completion was performed over the past few months by a concerted effort of a new author, who both incorporated long-standing feedback from the working group and worked out some of the finer details of the document. No aspect of the discussion proved controversial. Document Quality The document received in-depth review from a small handful of working group participants, and the results of those reviews were incorporated into the final version. No implementations of the protocol described in the document are known to exist yet; however, some of the problems addressed by the draft have been concretely demonstrated at the SIPit 31 interop event (which also highlighted some previously unnoticed problems with dual-stack address resolution). Dan Wing provided expert review for interaction with "Happy Eyeballs" techniques. Personnel Adam Roach is the document shepherd. Ben Campbell is the responsible area director.
