The IESG has received a request from the Session Initiation Protocol Core WG (sipcore) to consider the following document: - 'Locating Session Initiation Protocol (SIP) Servers in a Dual-Stack IP Network' <draft-ietf-sipcore-dns-dual-stack-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-07-04. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-sipcore-dns-dual-stack/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-sipcore-dns-dual-stack/ballot/ No IPR declarations have been submitted directly on this I-D.
