This paper proposes a protocol to support mobile hosts in IPv6 by introducing a new addressing architecture and a new hop-by-hop option. This protocol also allows a mobile host to communicate with another host via a firewall machine which drops packets from untrustworthy hosts. The new addressing scheme is based on the separation of the identifier and the location of a mobile host. This is a straightforward implementation of the basic concept of VIP, a protocol providing seamless mobility in IPv4. The new hop-by-hop option of IPv6 allows a firewall machine to authenticate the source host of the forwarded packet with negligible overhead. The author plans to implement this protocol on several operating systems in the near future.
