当我在 Google 上搜索 IP 地址时，会返回许多结果，其中一些会告诉不同城市的 IP 地址。

如何从 IP 地址中找到位置？

The reason you are getting different results is that there are different geolocation databases. Each of them returns a different result. In fact, there are studies to the reliability of these geolocation databases (e.g. http://www.caida.org/publications/papers/2011/geocompare-tr/).

In my experience, this one is pretty reliable:

https://iplocation.tools

You should compare multiple databases and figure out which is the most probable location yourself.

公平地说，您必须考虑到用户可能在代理服务器后面。

一般术语是地理 IP 查找或地理 IP。了解这一点的最佳方法是拥有一个与区域相关的 IP 地址的最新数据库。

这是 Ruby 中的一个模块：http: //www.chipstips.com/? p=524

注意：这是非常不准确的，并且基于已发布的表格可能无法保持准确。

它不准确的原因之一是因为 NAT 后面的任何 IP 都会报告最外层 NAT 网关的位置。因此，它通常在您的 ISP 甚至之外。

查看http://www.iplocation.net/ ，其中列出了 4 个用于将 IP 映射到地理位置的地理位置提供程序。

该链接还链接到由 James A. Muir 撰写的名为“Internet Geolocation and Evasion”的文档http://www.ccsl.carleton.ca/~jamuir/papers/TR-06-05.pdf 。在文档中，Muir 确定了 9 种方法及其局限性，以获取用户的地理位置数据。

You can use some API service for that.

For example, https://apiip.net , their API provides a lot of info about the IP, also you can request XML responses if needed.

Simple GET call:

https://apiip.net/api/check?ip=67.250.186.196&accessKey={your_api_key}

Response:
