| 1. A method for configuring a portable and/or mobile host that powers up in a foreign network to connect to the Internet,
comprising the steps of
creating a bootstrapping agent in the home network that works cooperatively with a Mobile IP home agent to initially allocate
a temporary home address to said portable and/or mobile host that powers up in the foreign network,
the portable and/or mobile host using the Mobile IP protocol to contact said Mobile IP home agent and request said bootstrapping
agent to allocate said temporary home address to said portable and/or mobile host while the mobile host is in the foreign
network;
using in the foreign network, said temporary home address to create a temporary tunnel between a foreign agent associated
with said portable and/or mobile host and said Mobile IP home agent, wherein said temporary tunnel is used to communicate
configuration information including a permanent home address allocated by a Dynamic Host Configuration Protocol (DCHP) server
between the portable and/or mobile host and its home network, when the portable and/or mobile host powers up in the foreign
network, thereby allowing the portable and/or mobile host that powers up in a foreign network to connect to the Internet;
and replacing said temporary tunnel with a new tunnel between said mobile IP home agent and said foreign agent using said
permanent home address, thereby allowing a mobile host without an IP home address to connect to the Internet when powering
up in the foreign network.
