Technical Summary

   The document defines the necessary Dynamic Host Configuration
   Protocol (DHCPv4 and DHCPv6) options that contain a list of domain
   name or IP addresses that can be mapped to servers providing IEEE
   802.21 type of Mobility Services [MSFD]. These Mobility Services
   are used to assist an MN in handover preparation (network discovery)
   and handover decision (network selection). The services addressed
   in this document are the Media Independent Handover Services
   defined in [IEEE802.21].

Working Group Summary

   This is a product of the MIPSHOP WG. There has also been
   considerable discussion in the DHC WG about the way this
   draft used or uses options. The resulting document is
   not unanimously supported, but represents the rough
   consensus.

Document Quality

   There are no known implementations or vendor plans to implement
   the specification.
