Abstract To limit an access to a Web site which is not good from an educational standpoint. SOLUTION: The access limit system of a CATV cable MODEM that limits access to a Web site on the Internet from the cable MODEM is provided with an IC card 11 that is inserted to the cable MODEM and on which a user ID and addresses of Web sites to which access is to be rejected are registered and with an access limit section 13 that rejects the access to a Web site going to be accessed when the address of the Web site going to be accessed is included in addresses of Web sites registered in the IC card. Preferably, the access limit section disposes of data received from a Web site when a received message includes any address of Web sites registered on the IC card 11.
