"Homage to the original Niuguozhu- http://www.iamniu.com/2012/03/10/geographical-orientation/"

Geographical orientation relies on the recognition of IP address, and IP protocol is the foundation of Internet Protocol, so from the first day of the birth of the network, the geographical orientation can be used.

In layman's terms, the IP address is the number on the Internet, all the hosts that access the Internet is one of our homes, which have a personal, there are units. Personal Residence A house number, the units of the common use of a house, due to the planning reasons, some dwellings will have multiple house number, but also planning reasons, the house number will sometimes change. The IP address is also characterized by the ability of a host to have multiple IP addresses, and a multi-state host can share an IP address.

In reality, no matter how you plan, you can find the place we are looking for by building the house number, and we can also know where the residence is located. Similarly, in the network, through the IP address can also locate the host we need to find, and clearly know the location of the host. This will enable the geographical orientation of the advertisement.

　　

Technically speaking, the working logic of geo-orientation is:

When a request is sent to the server, the server composes the log file according to the data requested by the configuration, and the log will basically include the request time, the request IP, the requested URL, the requested Reffer, the requested user-agent, and other information. The collected IP address is compared to an existing IP database, that is, the location of the requester can be determined. Of course, the requested IP information can be obtained from the HTTP protocol, and contempt must depend on the log.

The current geographical orientation is more targeted to the provinces and cities, the orientation of the county-level or district-oriented basic is very inaccurate.
