Pseudo-static IP implementation method and system based on dynamic IP

Abstract

The invention discloses a pseudo-static IP implementation method and system based on a dynamic IP. The implementation method comprises the following steps that: a host sends the dynamic IP of the host to a private library on a third-party public network in a timed manner; when a client machine needs to communicate with the host, the client machine obtains the dynamic IP of the host from the private library on the third-party public network; the client machine establishes connection with the host by utilizing the dynamic IP of the host; and the client machine performs data communication with the host after the connection is established. According to the invention, the host sends the dynamic IP to the private library on the third-party public network in a timed manner; when the client machine needs to communicate with the host, the client machine establishes connection with the host by utilizing the dynamic IP obtained from the private library on the third-party public network; then, data communication is carried out; and thus, the scheme is relatively low in cost and simple to operate and can satisfy most of static IP requirements.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and system for realizing pseudo-static IP based on dynamic IP. Background technique [0002] The Internet, also known as the Internet, or transliterated as the Internet or the Internet, is a huge network connected in series between networks. These networks are connected by a set of common protocols to form a logically single huge international network. This method of interconnecting computer networks can be called "network interconnection", and the global Internet covering the whole world developed on this basis is called the Internet, that is, a network structure that is interconnected. In order to realize communication between different hosts in the Internet, it is necessary to assign an address to each host. In the Internet, this address is called IP address, referred to as IP. IP includes static IP and dynamic IP. Static IP refers to the long-term fixed allocation to a ce...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the distribution of static IP requires expensive fees and the limited number of IPv4 addresses cannot satisfy all static IP requirements
