    abstract =  {This document defines a new Dynamic Host Configuration Protocol (DHCP) option with sub-options. One sub-option may be used by a DHCP client to provide mobile IP related identity information to the DHCP server. Another sub-option may be passed from the DHCP Server to the DHCP Client to announce the presence of one or more mobile IP Mobility Agents. For each announced Mobility Agent, information is provided which is the same as that of the classical Mobile IP Agent Advertisement extension to ICMP Router Advertisements.},
