Abstract
A method of associating a range of destination IP addresses with a real IP address for use with the Virtual Address Resolution Protocol is disclosed. The destination addresses may be a range of virtual IP addresses in a virtual network or a range of real IP addresses in a physical network. A record of the association of the range of destination addresses with a single real IP address is stored in a Virtual Address Resolution Protocol lookup table which is utilized when sending messages from a virtual IP address. The ability to assign a range of destination addresses to a single real IP address represents an extension of the use of VARP. The association of multiple destination addresses to a single real IP address allows an electronic device to function as a router to a widely distributed real or virtual network. The virtual network of the present invention adds a layer of encryption to the originating virtual network by sending encrypted data packets between the origin and destination addresses.
