The free version supports 5 subdivided lines: China Telecom, China Mobile, China Unicom, Education Network and search engine (Baidu). The advanced defense version supports provincial-level operator lines, as well as over 170 subdivided lines covering Hong Kong, Macao, Taiwan, five continents overseas and various countries. For details, please refer to Intelligent Cloud DNS Version Comparison.
The importance of subdivided lines lies in their ability to automatically detect that a visitor's address is "Beijing Unicom" and intelligently return the corresponding server IP for "Beijing Unicom," enabling more accurate server redirection for visitors.
