The IESG has approved the following document: - 'Essential correction for IPv6 ABNF and URI comparison in RFC3261 ' <draft-ietf-sip-ipv6-abnf-fix-05.txt> as a Proposed Standard This document is the product of the Session Initiation Protocol Working Group. The IESG contact persons are Robert Sparks and Gonzalo Camarillo. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-sip-ipv6-abnf-fix-05.txt Technical Summary This memo corrects the Augmented Backus-Naur Form (ABNF) production rule associated with generating IPv6 literals in RFC3261. It also clarifies the rule for Uniform Resource Identifier (URI) comparison when the URIs contain textual representation of IP addresses. Working Group Summary This document had consensus in the SIP Working group. Document Quality This document received a high level of review and implementation. Personnel Robert Sparks is the responsible area director RFC Editor Note In Section 5. Security Considerations OLD: This document does not introduce any new security considerations. NEW: This document does not introduce any new security considerations beyond those described in [1]. In section 3.1: OLD: Accordingly, this document updates RFC3261 as follows: the <IPv6address> and <IPv4address> production rules MUST be deleted from RFC3261 and MUST be replaced with the production rules of the same name in RFC3986 (and reproduced above.) These changes, when made to RFC3261, will make <hexpart>, <hexseq>, and <hex4> production rules obsolete. Thus this document also mandates that the <hexpart>, <hexseq>, and <hex4> production rules MUST be deleted from the ABNF of RFC3261. NEW: Accordingly, this document updates RFC3261 as follows: the <IPv6address> and <IPv4address> production rules from RFC3261 MUST NOT be used and instead, the production rules of the same name in RFC3986 (and reproduced above) MUST be used. This will render <hexpart>, <hexseq> and <hex4> production rules in RFC3261 obsolete; as such, these three production rules --- namely, <hexpart>, <hexseq> and <hex4> --- from RFC3261 MUST NOT be used. The use of the <IPv4address> production rule from RFC3986 no longer allows syntactically valid --- though semantically invalid --- SIP URIs of the form "sip:bob@444.555.666.777". _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
