Abstract

The invention relates to a method for obtaining an accurate geographical position based on IP address information. The invention has the key points that a computer terminal is preserved in a location information database by an IP address (IPv6) dynamically distributed by a DHCP server, an IP address and a port number (IPv4) translated by an NAT gateway/a router as well as the accurate geographical position information of the computer terminal obtained by that a wideband accesses a server, and is published to be location information WEB service supplied for website visiting; a website visits the location information WEB service according to the IP address information of the computer terminal which is interacted with the website to obtain the accurate location information of the computer terminal, thereby personalized service based on the accurate location information is provided for a computer user.

Description

technical field [0001] The present invention relates to a metropolitan area network (MAN: Metropolitan Area Network) and the Internet, and in particular to a method for obtaining precise geographic location information of a computer terminal based on the IP address information of the computer terminal. Background technique [0002] Computer terminals access the Internet by accessing the MAN. At present, the common access methods in China include ADSL (Asymmetric Digital Subscriber Line: Asymmetric Digital Subscriber Line) access and Ethernet access. The general mode for a computer terminal to access the Internet is as follows: the computer terminal is connected to the access node (AN: Access Node) of the access layer of the metropolitan area network through the client access equipment (CPE: Customer Premises Equipment), and then transmitted through the metropolitan area network The network is connected to the broadband access server (BRAS: Broadband Remote Access Server) at ...
