KR20010095814A - A Method and System of Specific Server Program Operation Using Dynamic IP Address - Google Patents

Abstract

PURPOSE: A method for operating specific server program with dynamic IP(internet protocol) address and a system of the same are provided to operate a specific server program in a cheap line using a dynamic IP address by recording the dynamic IP address and enabling a user to use the dynamic IP address. CONSTITUTION: A first process inquires an IP address of a server program or a sub program, and records the IP address at an arbitrary place. A second process records a dynamic IP address at a specific position or at a database through a home page CGI(common gateway interface) or an arbitrary server program. A third process inquires the IP address in the specific position or in the database, and accesses the dynamic IP address server which is wanted. A fourth process inspects a change of the IP address periodically and reestablishes the address.

Description

A method and system of specific server program operation using dynamic IP address

Computers using the conventional variable IP are assigned an arbitrary IP address from a DHCP server every time the system is booted. Therefore, since the IP address is not fixed, general users cannot know the address, and the computer cannot run the server program.

Therefore, an object of the present invention is to record a variable IP in any place (for example, homepage) that all users know that the IP is fixed, so that the user can use it first to find out the IP so that a specific server can be operated. have.

This allows certain server programs to run on inexpensive lines that use dynamic IP addresses.

1 is a block diagram showing the components required to access a server of a dynamic IP address from a client in the Internet network

The specific server program operation method and system using the dynamic IP address to achieve this purpose is shown in Figure 1.

(1) is a computer which wants to run a specific server program using a floating IP address.

(2) a specific server program run on a computer.

(3) is a computer using a static IP.

(4) is (3) homepage or IP recording program operated by computer.

(5) consists of client program for general users

(1) A computer is a computer using an inexpensive cable TV network using a dynamic IP address or an ADSL network.

(2) The program is a specific program that the operator wants to service. Besides the function to service, it finds the IP of the current computer and connects to the server (3) which is already known as HTTP protocol or TCP / IP protocol. Include.

The computer using static IP (3) has a known Internet domain name address. The homepage domain name is almost unchanged once it is set up, so if you know the domain name, you can easily find out the static IP through DNS.

(4) The program is composed of CGI or script language in the case of homepage type, and in the case of IP recording program, it opens a specific port and waits. They record the IP address passed by the program via TCP / IP or HTTP protocol in an arbitrary place or database.

(5) The client program for general users has the function to inquire the IP address recorded by program (4) in addition to the function to be serviced, and (2) to access the program.

It is a program module that runs on web browsers such as ActiveX or Java, or it is composed of regular programs.

The actual connection process is as follows.

Server side

(1) A dynamic IP address is assigned from the DHCP server when the computer boots.

(2) Find out the current computer's IP at the start of the program and pass it to the HTTP protocol (4). In the middle of the program, check the IP at the set time period and repeat the above operation if there is a change.

(4) The program records the address passed in (2) in a specific area or stores it in a database.

Client side

(5) The program searches the specific location or database recorded by (4) at the beginning.

Find out the IP.

(2) Access the server program with the found IP and receive service.

(3) In the middle of the program, check the IP at the set time period and repeat the above operation if there is a change.

As described above, the present invention can operate a specific server even on an inexpensive line using a dynamic IP address such as ADSL or cable TV network.

Claims (1)

A method of operating a server on a dynamic IP address line, the method comprising: querying an IP of a server program or an auxiliary program itself, and passing the data to an arbitrary known location; A step in which a homepage CGI or an arbitrary server program records a floating IP address in a specific location or database in a server whose address is known; A client querying an IP from a specific location or a DataBase in a server whose address is known and connecting to a desired floating IP address server; Method and system for accessing a server using a floating IP address including checking the change of IP address at regular intervals and resetting the address by repeating the above record and inquiry if there is a change
