IP (Internet Protocol) address configuration method

Abstract

The invention discloses an IP (Internet Protocol) address configuration method. The IP address configuration method is applied to a router embedded linux system, and is characterized in that the embedded linux system includes a data structure, and the data structure stores an IP address which has been used in a current local area network; the IP address configuration method further comprises the steps of analyzing an IP address of a terminal when the terminal sends and receives a data packet through a router, and comparing the IP address with the IP address in the data structure; and if a comparison result shows that the IP address of the terminal has been used, then reallocating an IP address for the terminal or providing an available IP address for the terminal reconfiguration. According to the IP address configuration method provided by the invention, by detecting the IP address conflict of the terminal at a router end, and performing reallocation or prompting on the IP address that has the conflict, more efficient IP address resetting can be realized, the workload of manual contrast and query can be reduced, and the IP address reset efficiency can be improved.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to an IP address configuration method. Background technique [0002] IP (Internet Protocol) means a protocol for interconnection between networks. It is a protocol designed for computer networks to communicate with each other. It enables all computer networks connected to the Internet to communicate with each other and stipulates that computers communicate on the Internet. rules to be followed. Computer systems produced by any manufacturer can be interconnected with the Internet as long as they comply with the IP protocol. Because of the IP protocol, the Internet has rapidly developed into the world's largest and open computer communication network. Therefore, the IP protocol can also be called the "Internet Protocol". [0003] IP address (Internet Protocol Address) refers to the Internet protocol address. IP address is a unified address format provided by the IP pr...

Problems solved by technology

IP address conflicts will cause network interruption and seriously affect the normal use of the network

At present, the commonly used method to solve the IP address conflict is to detect the IP address conflict on the terminal side. After detecting the IP address conflict, the user needs to manually check the allocated IP address, and then find the unallocated IP address and set it as the terminal IP address. , this method requires manual search and setting one by one, which is inefficient
