Method and device for determining physical location information

Abstract

The invention discloses a method and device for determining physical location information. The method comprises the following steps: selecting preset quantity of reference IP addresses, and establishing a network coordinate system comprising the reference IP addresses and to-be-processed IP addresses, wherein physical location information of the reference IP addresses is determined; delimiting an identifiable area of the to-be-processed IP addresses in the network coordinate system; and determining the physical location information of the to-be-processed IP addresses according to the physical location information of the reference IP addresses in the identifiable area. By adopting the scheme, the dependency level on third party data when the physical location of the to-be-processed IP addresses is determined can be reduced or even removed, and the accuracy of determining the physical location is improved. Meanwhile, compared with an existing mode of deducing the physical location information according to the search result of the third party, the method has the advantage that the accuracy of the physical location is improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for determining physical location information. Background technique [0002] IP (Internet Protocol, a protocol for interconnection between networks) is a protocol designed for computer networks to connect and communicate with each other. In the Internet, IP is a set of rules that enable all devices connected to the Internet (such as computers, mobile terminals, tablet computers, and other devices that can access the Internet) to communicate with each other, and it specifies the rules that devices should abide by when communicating on the Internet. rule. At the same time, in order to ensure the correct communication between any two devices in the network, the IP protocol also assigns a unique address to each device connected to the Internet, that is, an IP address, based on which the device can transmit information. [0003] With the continuous development o...

Problems solved by technology

[0007] From the above-mentioned process of determining the physical location information, it can be seen that the prior art relies heavily on third-party data (such as preset databases, SNS, etc.), and when the third-party data deviates, it will inevitably affect the accuracy of the final determined physical location. sex

In addition, the existing technology can only perform coarse-grained location inference, which generally infers the physical location of the IP address of the backbone network, and the accuracy is poor.
