This paper introduces and implementes a query-driven, distributed network platform QDA ( Query-Driven distributed IP address location platform).

QDA is fault tolerant and provides fast query and batch query interface, which makes it has better performance than traditional network resource databases.

平台中数据可查询驱动、动态扩充；同其它传统的网络资源库相比，QDA在快速查询和支持批量查询方面具有明显优势。
