Description

E-mail address based internet communication method and recording media therefor}

The present invention relates to an internet communication method, and more particularly, to an internet communication method and a recording medium thereof capable of performing internet communication between clients based on an email address.

Computer communication based on computer networks has been used primarily in high performance small computers such as workstations. However, as PCs are widely used and access services to the Internet, which are computer networks with a global scale, are commercially available, computer communication through the Internet is widely activated. Computer communication based on the Internet can be divided into server-client communication and client-client communication. Server-client communication occurs mainly when a user accesses a specific site through his web browser and receives a desired service. Client-client communication is used when a file transfer protocol (FTP) service or a multimedia file is to be transferred.

To communicate with a computer via the Internet, you need an IP address. An IP address is a 32-bit address given the concept of matching a physical network address for efficient routing on the Internet. In general, a user subscribes to an Internet access service provider and receives an IP address, and accesses the Internet through the provided IP address. IP addresses provided to subscribers are classified into fixed IP addresses and fixed IP addresses. The fixed IP address is an IP address fixedly assigned only to the subscriber, and the variable IP address is an IP address dynamically assigned every time the Internet is connected, unlike the fixed IP address. The variable IP address is created as a way of sharing the IP address among multiple subscribers by allocating an IP address which is not currently used among the IP addresses secured by the Internet access service provider when the subscriber requests Internet access.

Therefore, subscribers who are assigned a fixed IP address can use the IP address to operate the server as well as receive various services from the outside. In order to receive various services provided from the outside, such as FTP, it is difficult to inform the external service provider or the communication counterpart of the IP address that is changed every time.

Of course, even in the case of the variable IP address, there is no problem in the server-client communication in which the subscriber requests a service from an external server. Because TCP (Transfer Control Protocol) is based on connection-oriented communication, it provides the server with the current IP address when requesting service. However, when data is input from the outside to the subscriber's computer, it is necessary to inform the outside service provider or communication counterpart of the subscriber's variable IP address. In fact, in the case of a transmission service of large data such as a multimedia file for games, a subscriber is receiving a file by informing a service provider of his / her current IP address by telephone.

Accordingly, an object of the present invention is to provide an email address-based Internet communication method and a recording medium thereof, which can easily communicate with a computer via the Internet even in the case of a subscriber having a variable IP address or a private IP address.

The hub 400 is connected to the Internet. In this case, the host computer 40 has a public IP address, but the communication counterpart computers 401, 402, 403 have a private IP address. A public IP address is an IP address that is assigned from a public registrar and registered in a DNS (Domain Name Server) to communicate on the Internet. A private IP address is an address that is only used within a specific network. In addition, both the user computer 3 and the counterpart computers 401, 402, 403 are provided with a communication program for communicating between clients via the Internet based on an e-mail address according to a preferred embodiment of the present invention.

Referring to FIG. 1C, both the user and the communication counterpart are connected to the Internet through the hosts 30 and 40 of the subnetwork. That is, the user computers 301, 302, 303, which are user terminals, are connected to the host computer 30 of the user side subnetwork through the hub 300, and the communication counterpart is connected to the host computer 40 of the sub network on the communication counterpart side as in FIG. 1B.

However, "year / month / day" or " Year / month / day / hour / minute ”.

The communication module 105 extracts the IP address of the communication counterpart from the email received by the email transmission / reception module 103 when the email address input through the user interface module 102 is a new email address which is not stored previously. In the case of the previously stored e-mail address, when the comparison result of the comparison module 104 determines that the input time and the use time of the e-mail address are the same, the most recently used IP address is extracted and applied to the extracted IP address. Allow data to be transmitted so that program 110 can be executed. On the other hand, even if the e-mail address received through the user interface module 102 is a pre-stored e-mail address, when the comparison result by the comparison module 104, when it is determined that the input time and use time of the e-mail address is different from each other, Data is transmitted to the new IP address extracted from the email received by < RTI ID = 0.0 > 103. < / RTI >
