Introduction This specification defines the addressing architecture of the IP Version 6 (IPv6) protocol. It includes the basic formats for the various types of IPv6 addresses (unicast, anycast, and multicast). The authors would like to acknowledge the contributions of Paul Francis, Scott Bradner, Jim Bound, Brian Carpenter, Matt Crawford, Deborah Estrin, Roger Fajman, Bob Fink, Peter Ford, Bob Gilligan, Dimitry Haskin, Tom Harsch, Christian Huitema, Tony Li, Greg Minshall, Thomas Narten, Erik Nordmark, Yakov Rekhter, Bill Simpson, Sue Thomson, Markku Savela, and Larry Masinter. 2. IPv6 Addressing IPv6 addresses are 128-bit identifiers for interfaces and sets of interfaces (where "interface" is as defined in section 2 of [IPV6]). There are three types of addresses: Unicast: An identifier for a single interface. A packet sent to a unicast address is delivered to the interface identified by that address. Anycast: An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the "nearest" one, according to the routing protocols' measure of distance). Multicast: An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to a multicast address is delivered to all interfaces identified by that address.Show full document text
