Method and device for modifying IP address of equipment

Abstract

The invention discloses a method and a device for modifying the IP address of equipment. The method comprises the following steps that: first equipment broadcasts an activation request to all equipment in a local area network and receives an activation response, wherein the activation response comprises equipment basic information of the equipment initiating the activation response; and when determining that the equipment initiating the activation response is nonactivated equipment according to the equipment basic information, the first equipment adds the nonactivated equipment as activated equipment, and initiates an IP address updating request to the activated equipment, wherein the IP address updating request comprises the IP address and port number specified by the activated equipment. Through the method and the device, the IP address of the equipment can be efficiently modified and can also be remotely controlled.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for modifying an IP address of a device. Background technique [0002] For a device with an unknown IP address, it is impossible to control and manage the device through client or server software. That is to say, the existing software for remote control and management of equipment through the network is based on the premise that the IP address of the equipment is known, so that information such as the IP address and subnet mask of the equipment can be modified. [0003] At present, the way to modify the IP address of a new networked device is to connect the new networked device to the client or server application software through a serial port, obtain the initial device IP address of the device to be activated, and then modify the IP address according to the requirements of the current network. The initial device IP address (usually the initial device ...

AI Technical Summary

Problems solved by technology

Since the equipment such as the network camera has been packaged before leaving the factory, it is necessary to open the package one by one to connect to the serial port, thereby modifying the IP address of each device, and the modification efficiency is low;

[0006] 2) The operation is inconvenient, because it needs a serial port line, it can only adapt to the short-distance connection, and cannot realize remote control
