The invention provides an Internet IP address positioning data-based IP address positioning system and an Internet IP address positioning data-based IP address positioning method. The system includes a data extraction layer, a data processing layer, a data storage layer and a verification fusion layer. The method includes the following steps that: configuration parameters are initialized, and normalization processing is performed on acquired Internet IP address positioning data; reverse verification is performed on the Internet IP address positioning data; and the Internet IP address positioning data are fused. According to the Internet IP address positioning data-based IP address positioning system and method of the invention, a plurality of Internet IP address positioning databases are integrated, so that the Internet IP address positioning databases can complement each other and improve each other, and therefore, data coverage can be improved; memory mirroring is utilized to carry out data entry, so that efficiency can be greatly improved; and reverse verification and trust-based data fusion techniques are adopted, so that the accuracy of data can be improved.
