ABSTRACT:
A preferred embodiment of the present invention includes a method and apparatus for allocating and using IP addresses in a network of client systems. More specifically, the present invention includes a router which monitors the assignments of IP addresses by a DHCP server. As each IP address is assigned, the router associates the assigned IP address with an trusted identifier which identifies the client system. Subsequently, if the router received a packet directed at the assigned IP address, the router forwards the packet to the client system having an trusted identifier associated with the destination address of the IP packet. Additionally, if the router receives a packet from a client system, it uses the trusted identifier of the client system to find IP addresses associated with the client system. If the source address of the IP packet is not included in the IP addresses associated with the client system, the packet is discarded.
