IETF - Mobility EXTensions for IPv6 (MEXT)

Mobile IPv6 specifies routing support which permits an IPv6 host to continue using its home address as it moves around the Internet, enabling continuity of sessions. Mobile IPv6 supports transparency above the IP layer, including maintenance of active transport level sessions. In addition, NEMO network mobility mechanisms built on top of Mobile IPv6 allow managing the mobility of an entire network, as it changes its point of attachment to the Internet. The base specifications consist of:
 * RFC 3775
 * RFC 3963
 * RFC 4877

The MEXT Working Group continues the work of the MIP6, NEMO, and MONAMI6 Working Groups.

The primary goal of MEXT will be to (A) enhance base IPv6 mobility by continuing work on developments that are required for wide-scale deployments and specific deployment scenarios.  Additionally, (B) the working group will ensure that any issues identified by implementation and interoperability experience are addressed, and that the base specifications are maintained. (C) The group will also produce informational documentation, such as design rationale documents or description of specific issues within the protocol.
