DHCP Options for Home Information Discovery in Mobile IPv6 (MIPv6)
Abstract
This document defines a DHCP-based scheme to enable dynamic discovery
of Mobile IPv6 home network information. New DHCP options are
defined that allow a mobile node to request the home agent IP
address, Fully Qualified Domain Name (FQDN), or home network prefix
and obtain it via the DHCP response.
