Multiaddressing — Mobility and multihoming

These cover two sides of the same set of requirements, called multiaddressing. The goal is to preserve associations across locator (address) changes. An association is shared state, such as a transport connection. Mobility and multihoming each include requirements from the other. A mobile host needs to support old and new locators at the same time, as does multihoming. A multihomed host needs to add and remove addresses; as does mobility. Site renumbering is a special case of multihoming
