Abstract
An address determination apparatus that determines a valid address that a communication apparatus designates as the address at which a communication starts for indicating the origin of a transmission includes: a duplicate valid address determination means that selects a tentative address, and by an inquiry on a network, determines the existence of a valid address that duplicates the tentative address in the network; a memory means that stores the tentative address as an uncertain address when it is determined by the duplicate valid address determination means that there is no valid address that duplicates the tentative address in the network; and an address determination means that, when a communication apparatus begins communication that designates the address at which the transmission originates, determines the uncertain address that is stored in the memory means as the valid address designated as the address at which the transmission of the communication apparatus originates.
