<p>In a communication apparatus and a communication method, identification information statically allocated to a remote communication apparatus is designated, and a domain name of the remote communication apparatus is presented to acquire an IP address by using a DNS service. A connection is made to a remote communication apparatus, to which the IP address acquired is allocated, to receive a response message. Information included in a predetermined section of the response message and all or a predetermined part of identification information designated are compared. When all or the predetermined part of the identification information coincides with the information included in the predetermined section of the response message, substantive data is transmitted to the remote communication apparatus connected. Prevents transmission of data to the incorrect apparatus if, due to network error, the IP address is subsequently allocated to a different apparatus. Applicable to peer-to-peer networks and may be used for reliable transmission of facsimiles across an IP network.</p> |
