When discussing IPv6 deployment related matters it is easy to mix up the terminology used in this area. To try to provide a higher level of consistency in this area this document suggests a brief terminology definition that may be used as a reference when using IPv6 deployment related terminology.

This document is intended to serve as a reference to IPv6 deployment related terminology. It is not the purpose of this document to introduce any new terminology into this area but only to provide definition of already existing and established terminology.

IPv6 deployment is the process of introducing IPv6 in a network environment, be it an environment where currently IPv4 is in use and the two IP versions co-exist or in a "Greenfield" deployment with no prior IP infrastructure. IPv6 deployment in co-existence with an IPv4 environment may or may not have the goal of completing an IPv6 migration. IPv6 deployment can be discussed from a node capability perspective as well as from an application capability perspective.
| TOC |
IPv6-only defines a state where only IPv6 is available for IP transport. The limitation can reside in applications and/or node capability.
| TOC |
IPv6 migration is the process of switching from IPv4 to IPv6 in a node or a network.
| TOC |
IPv6 transition defines the task of making the transition of the Internet to IPv6-only as the final stage of the IPv6 migration process. IPv6 transition mechanisms [RFC4213] (Nordmark, E. and R. Gilligan, “Basic Transition Mechanisms for IPv6 Hosts and Routers,” October 2005.) are designed to enable transition and to support IPv6 hosts and routers that need to interoperate with IPv4 hosts and utilize IPv4 routing infrastructures.

Once upon a time there where two countries, IPv4 and IPv6. IPv4 was a crowded country with limited resources and a growing population tormented by starvation and diseases. On a distant shore across the sea was a brave new land, full of promises and plenty, called IPv6. Spurred by the opportunities of a better life in the distant country families started the process of migrating from their old country IPv4 to IPv6. In their new homeland the people there spoke another language called IPv6, while the newcomers only spoke IPv4, the language of their old country. Luckily many of the people that already lived in IPv6 also spoke IPv4, and being bi-lingual made it possible for them to talk to their new fellow countrymen and to introduce them to the language of their new country. Eventually the immigrants also became bilingual and for some their frequent use of their new won language they made the transition from speaking IPv4 to IPv6. I was also common that the children of the immigrants only spoke IPv6, which was made possible because of the bi-lingual skills of their parents. Some of the older people, like grandparents than accompanied the families, kept their old habits and language which they spoke among their kin and friends from the old country. To talk with their grandchildren they had to rely on the bilingual parents to translate between children and grandparents. Eventually the need of being bi-lingual became less important as time went by, and when the need will go away only time can tell.
Bi-lingual read Dual-Stack
Starvation and diseases read Address pool depletion
Migrate - move from one country or region to another and settle there
Transition - a change of state
