Problems solved by technology

[0004] However, in the prior art, after the off-net terminal automatically generates its own IP address, it still needs to send a detection message to other off-net terminal devices in the network to ensure that its own IP address is unique, which obviously increases the network load.
[0005] In addition, after the off-network terminal automatically generates an IP address, it needs to obtain the IP address of the peer device through the domain name system DNS in order to communicate with the peer device. The IP address is unique, but because this method can only generate its own IP address, but cannot obtain the peer IP address, it still cannot achieve end-to-end communication

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0056] The present invention mainly uses a certain unique identifier of the off-network terminal itself in the network, converts it into an IP address through a specific algorithm, and guarantees the uniqueness of the converted IP address with the uniqueness of the unique identifier, so there is no need to send a uniqueness detection message. In addition, the off-net terminal can use the same algorithm to obtain the IP address of the peer end through the unique identifier of the peer end, so that end-to-end communication can be realized without the support of the DNS system.

[0057] figure 1 For the IP address automatic generation method flowchart of the embodiment of the present invention, as figure 1 As shown, the method includes the following step...

Abstract

The embodiment of the invention discloses a method for automatically generating an Internet protocol (IP) address of an off-line terminal. The method comprises the following steps of: acquiring a unique identifier of the off-line terminal in a network; extracting the unique identifier to be a digital middle code of a preset bit; and converting the middle code into the IP address through a binary-coded decimal (BCD) method or a bit fetching method. The invention also discloses a device for automatically generating the IP address of the off-line terminal. By the method and the device, the off-line terminal can guarantee the uniqueness of the IP address of the off-line terminal without sending a detection message.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for automatically generating an IP address of an off-network terminal. Background technique [0002] Currently, in many communication systems, the automatic generation of an IP address by a terminal device is mainly realized by interacting with a server through a Dynamic Host Configuration (DHCP) protocol. [0003] When all the terminal devices in the network are running offline, if a terminal device in the network that executes the DHCP service fails, the terminal device cannot obtain an IP address, and the communication between the terminal devices cannot be realized; in order to solve the problem of offline status, The terminal device does not obtain the IP address through DHCP. In the prior art, the terminal usually adopts a certain strategy to realize the automatic generation of the IP address, so that the off-network terminal can realize en...
