The IESG has approved the following document: - 'IPv6 Socket API for Source Address Selection ' <draft-chakrabarti-ipv6-addrselect-api-07.txt> as an Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Jari Arkko. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-chakrabarti-ipv6-addrselect-api-07.txt Technical Summary The IPv6 default address selection document [RFC3484] describes the rules for selecting source and destination IPv6 addresses, and indicates that applications should be able to reverse the sense of some of the address selection rules through some unspecified API. However, no such socket API exists in the basic [RFC3493] or advanced [RFC3542] IPv6 socket API documents. This document fills that gap by specifying new socket level options and flags for the getaddrinfo() API to specify preferences for address selection that modify the default address selection algorithm. The socket API described in this document will be particularly useful for IPv6 applications that want to choose between temporary and public addresses, and for Mobile IPv6 aware applications that want to use the care-of address for communication. Working Group Summary This document is not the product of an IETF working group. It has however been discussed on the IPv6 working group mailing list by key members of the community. There were some controversy about the design of the name to address function (getaddrinfo) extensions, but consensus has been that the extension maintains source compatibility, and binary compatibility except in rare use cases. Document Quality A couple of vendors have expressed their interest in implementing the specification. Jun-ichiro Hagino did a thorough review of the document that resulted in the current design of the name to address function (getaddrinfo) extensions. Geoff Huston from IP Directorate has reviewed the specification. Personnel Julien Laganier is the Document Shepherd for this document. Jari Arkko is the Responsible Area Director. Note to RFC Editor Please change "structre" to "structure" in Section 7. Please change the first sentence in the Security Considerations section as follows: OLD: This document conforms to the same security implications as specified in the Basic IPv6 socket API [RFC3493]. NEW: This document conforms to the same security implications as specified in the Basic IPv6 socket API [RFC3493] and address selection rules [RFC3484]. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
