An Internet protocol facsimile machine (IP-FAX or Fax-over-IP) 1 is connected to the Internet 6 via a router 4 and carries out communication by using a set communication port. The facsimile machine includes a function for setting and changing the communication port to be used by the facsimile machine itself, and a function for changing a port transfer setting of the router so that a packet addressed to the set and changed communication port is transferred to the facsimile machine itself. The fax machine includes a function for storing address information and account information of a prescribed remote server and a domain name of the facsimile machine itself, and a function for registering registration information including the domain name with the remote server device. The domain name of the facsimile machine is registered automatically with the remote server device, and therefore, without requiring an exclusive router, a dynamic domain name server (DDNS) 7 can be used, simplifying system architecture. |
