The present invention relates to a network connection device which can improve the velocity of processing for exchanging the address of the frame with use of a relatively simple structure. The network connection device of the present invention comprises CAMs, each having predetermined data stored in each of a plurality of entries in advance, for checking whether or not the predetermined data of each entry is conformed to data of the frame transmitted from a sender network, a table memory, provided to correspond to each entry of the CAM, for storing data of the other CAM to be searched next or an address of a destination sender network, and a data continuous search processing circuit for obtaining the address of the destination network of the frame from the sender network by use of data and the address stored in the table memory and the checking means when the CAM checks that the predetermined data is conformed to data from the sender network, for setting the address of the frame from the sender network in place of the address of the destination network having the address of the frame from the sender network obtained, and for transmitting the frame having the address of the destination network set to the sender network. According to the above- mentioned structure, the checking means is continuously accessed based on data sent from the storing means, so that the address of the network can be obtained. As a result, the velocity of the processing can be improved by use of the continuous search.
