	There have been several proposals to improve upon the Return
	Routability procedure defined in MIPv6 (RFC 3775), both in terms of
	the security of the mechanism as well as with respect to its
	performance. In particular, discussions within the MOBOPTS Research
	Group of the IRTF have centered on reducing the round trip times
	required to complete the procedure, and on increasing the length of
	time before the procedure needs to be run again. Some proposals are
	mature enough that they will be taken over by MIPSHOP for
	standardization.

			procedure by reducing the round trip times required to complete the
			procedure, and increasing the length of time before the procedure
