This document describes two algorithms, one for source address
selection and one for destination address selection. The algorithms
specify default behavior for all Internet Protocol version 6 (IPv6)
implementations. They do not override choices made by applications
or upper-layer protocols, nor do they preclude the development of
more advanced mechanisms for address selection. The two algorithms
share a common context, including an optional mechanism for allowing
administrators to provide policy that can override the default
behavior. In dual-stack implementations, the destination address
selection algorithm can consider both IPv4 and IPv6 addresses --
depending on the available source addresses, the algorithm might
prefer IPv6 addresses over IPv4 addresses, or vice versa.
Default address selection as defined in this specification applies to
all IPv6 nodes, including both hosts and routers. This document
obsoletes RFC 3484. [STANDARDS-TRACK]
This document is a product of the IPv6 Maintenance Working Group of the IETF.
This is now a Proposed Standard Protocol.
STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
