The present invention provides a network interface card (1) for selectively transferring data packets from a communications network to an end station using an address stored in an address field (56) of the data packet (60). The network interface card (1) includes a detector (11), which detects the address in the address field. An algorithm is then applied to the address to determine an address indication value associated with the address. A controller (13) then accesses a data store (14) the address indication value. A comparison is then carried out between any received addresses located in the data store with the address field of the data packet, with the transfer of the data packet to the output (3) being carried out in response to a successful comparison. |
