• the present invention has been made in view of such a situation, and an object of the present invention is to provide a technique for specifying personal information of a communication partner on a network.
• One embodiment of the present invention is a method for identifying personal information in a network in which a source host and a destination host belong to different local areas.
• a source host sends a request packet requesting a GUID (Global Unique Identifier) of the destination host to a destination host, and in response to the request packet, the destination host makes its own GUI.
• the destination host returns a response packet containing D; if the source host is the response packet Obtaining the GUID of the destination host from the host.
• the GUID of the destination host can be obtained from a remote location beyond the router.
• a personal information database that stores a GUID and personal information in association with each other may be provided at an arbitrary location on the network.
• the transmission source host obtains the response packet power and the like.

May be further stored. According to this, it is possible to charge for connection to the transmission source host.
• “Providing services from the source host to the destination host” includes starting software stored in the source host, referring to data, and using specific functions. The billing may be in units of access or units of use time.
• Another embodiment of the present invention is a network interface device.
• This device transmits a request packet requesting a GUID to a destination host when a packet is exchanged with a destination host belonging to a different local area, and responds to the request packet.
• a receiving unit that receives the response packet that includes the GUID of the destination host and that is transmitted from the destination host, and an obtaining unit that obtains the GUID of the destination host from the response packet. According to this, it is possible to obtain the GUID of the destination host from a remote location beyond the router.
• Still another embodiment of the present invention is directed to a database provided in an arbitrary place on a network and storing a GUID and personal information in association with each other.

• ARP Address Resolution Protocol
• ARP is used to know the MAC address corresponding to the destination IP address in the same segment (same rolling area). In this way, communication can be established between the source host and the destination host.
• a MAC address is an identifier that is unique worldwide. Therefore, if a database is created by associating the MAC address with the personal information, it is possible to identify the personal information of the communication partner by acquiring the MAC address for all communications on the network. .

• FIG. 1 a description will be given of a procedure in which the source host 10 acquires the MAC address of the destination host 30 when the computer 10 is a “source host” and the computer 30 is a “destination host”. It is assumed that IP communication has been established between the transmission source host 10 and the destination host 30, and the mutual IP addresses are known.
