RFC 5954, "Essential Correction for IPv6 ABNF and URI Comparison in RFC 3261", August 2010

Source of RFC: sip (rai)

Errata ID: 4929

Status: Reported
Type: Editorial

Reported By: David van Moolenbroek

Section 3.1 says:

   Because the <hexpart> production rule is defined such that two of its
   alternatives already include the "::" token, this may yield to the
   faulty construction of an IPv6-mapped IPv4 address with an extra
   colon when expanding those alternatives.

It should say:

   alternatives already include the "::" token, this may yield to the
   faulty construction of an IPv4-mapped IPv6 address with an extra
   colon when expanding those alternatives.

Notes:

The text refers to an IPv6 address, and thus should use the proper term "IPv4-mapped IPv6 address," in line with the section title, the rest of the document, and (in particular) RFC 4291.

Section 4.2, page 5 says:

   NEW:

   o  For two URIs to be equal, the user, password, host, and port
|     components must match.  If the host component contains a textual
|     representation of IP addresses, then the representation of those
      IP addresses may vary.  If so, the host components are considered
      to match if the different textual representations yield the same
      binary IP address.

Rationale: Essential clarification of potentially misleading grammar
and semantics including singular/plural mismatches. Because of the
perceived significance, this erratum is designated as Technical.
