Fast Handovers for Mobile IPv6 is described in {{IETF RFC|5568}}.

Researchers create support for mobile networking without requiring any pre-deployed infrastructure as it currently is required by MIP. One such example is Interactive Protocol for Mobile Networking (IPMN) which promises supporting mobility on a regular IP network just from the network edges by intelligent signalling between IP at end-points and application layer module with improved quality of service.

Researchers are also working to create support for mobile networking between entire subnets with support from Mobile IPv6. One such example is Network Mobility (NEMO) Network Mobility Basic Support Protocol by the IETF Network Mobility Working Group which supports mobility for entire Mobile Networks that move and to attach to different points in the Internet.  The protocol is an extension of Mobile IPv6 and allows session continuity for every node in the Mobile Network as the network moves.

=== Changes in IPv6 for Mobile IPv6 ===
*A set of mobility options to include in mobility messages
*A new Home Address option for the Destination Options header
*A new Type 2 Routing header
*New Internet Control Message Protocol for IPv6 (ICMPv6) messages to discover the set of home agents and to obtain the prefix of the home link
*Changes to router discovery messages and options and additional Neighbor Discovery options
*Foreign Agents are no longer needed
