The IESG has approved the following document: - 'Requirements for address selection mechanisms ' <draft-ietf-v6ops-addr-select-req-07.txt> as an Informational RFC This document is the product of the IPv6 Operations Working Group. The IESG contact persons are Ron Bonica and Dan Romascanu. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-v6ops-addr-select-req-07.txt > Technical Summary: One physical network can have multiple logical networks. In that case, an end-host has multiple IP addresses. (e.g., in the IPv4-IPv6 dual-stack environment, in a site that uses both ULA [RFC4193] and global scope addresses or in a site connected to multiple upstream IPv6 networks) For such a host, RFC 3484 [RFC3484] defines default address-selection rules for the source and destination addresses. Today, the RFC 3484 mechanism is widely implemented in major OSs. However, we and others have found that in many sites the default address-selection rules are not appropriate for the network structure. PS [I-D.ietf-v6ops-addr-select-ps] lists problematic cases that resulted from incorrect address selection. Though RFC 3484 made the address-selection behavior of a host configurable, typical users cannot make use of that because of the complexity of the mechanism and lack of knowledge about their network topologies. Therefore, an address-selection autoconfiguration mechanism is necessary, especially for unmanaged hosts of typical users. This document contains requirements for address-selection mechanisms that enable hosts to perform appropriate address selection automatically. > Working Group Summary: The problem statement and requirements have been thoroughly discussed and seem to have a reasonably strong consensus. The proposed solution is not yet agreed to. > Document Quality: This is not a protocol. It is a requirements statement for an operational policy procedure. RFC 3484 is implemented in several OS's.
