Method for acquiring dynamic IP address of server in real time

Abstract

The invention provides a method for acquiring a dynamic IP address of a server in real time. The method comprises following steps: a) that a proxy server confers access authority on an authorized server and a client user; b) that the authorized server submits verification information to the proxy server so as to verify the verification information and uploads the IP address of the authorized server to the proxy server after verification successes; c) that the proxy server updates the IP address of the authorized server and stores the IP address of the authorized server in a specific storage space; d) that a user submits the verification information with a client in order to have access to the proxy server and the proxy server returns extracted IP address of the authorized server that the user wants to have access to back to the client after verification succeeds; and e) that the user logs in the authorized server with the IP address returned from the client. The method authentically achieves a fact that a user is not required to purchase a static IP address with high price and saves cost. Access steps related to the invention are all required to be verified such that access security is guaranteed.

Description

Technical field [0001] The present invention relates to the field of network technology, to network IP address analysis, and in particular to a method for real-time obtaining a dynamic IP address of a server. Background technique [0002] Computers in the Internet can access each other through IP addresses. With the development of the Internet and enterprise informatization, IP resources are becoming more and more precious. In particular, fixed IP is increasingly scarce and very expensive, and many users cannot afford it. Without a fixed IP address, data communication can be realized by remote dialing or by telling the other party the IP address by telephone each time, but it is expensive, has poor stability and is not easy to maintain. [0003] For example, the application number is 201110138153.9 for the invention patent of "Real-time Obtaining Server Dynamic IP Address Technology", the method steps of this technology are as follows: [0004] (1) Assign a user name and password to...

Problems solved by technology

Moreover, in practical applications, users do not know the IP address of the server before accessing the remote server. If the user server has already accessed the user's client computer, the client does not need to obtain the dynamic IP address of the user server.

This defect has directly caused this invention to be unable to realize
