Abstract
A method for establishing a network connection between two computing devices within the same computer network includes the steps of generating a masquerade IP address request, where the masquerade IP address request includes a masquerade MAC address, transmitting the masquerade IP address request to a DHCP server, and receiving a masquerade IP address from the DHCP server. The masquerade IP address is then used as the sender's IP address in an ARP broadcast request transmitted to set up the network connection. Since the masquerade IP address is unique relative to the computer network, computing devices within the network do no overwrite existing IP-to-MAC relationships in their respective ARP caches with the IP-to-MAC relationship reflected in the ARP broadcast request. Thus, the method enables a network connection to be initiated between two computing devices in the same computer network while avoiding ARP cache pollution on other computing devices in that network.
