IP本地化：映射IP->位置固定的时间？ [英] IP localization: mapping ip->location fixed over time?

问题描述

我正在管理一个网络平台，并希望获得一些统计数据，我的用户来自哪里。我可以存储远程IP，并且我知道有本地化服务可将IP映射到地理位置。

这个映射是如何完成的？是否有固定的表格，哪个IP地址被分配到哪个区域？

我必须在访问时请求映射吗，还是可以请求它的日/月/年后来？换句话说：从IP到位置的映射是固定的还是随时间变化的？随着时间的推移而变化。我已经读过，数据库每个月都会变化5％，尽管很难知道它们是否真的改变了那么多，或者数据库提供商是否会更频繁地出售更新。但事实是这些数据库发生了变化。所以你应该尽快获得IP地址的位置，至少不要晚于捕获IP地址一个月后。

I'm administering a web platform and want to get some statistical data, where my users come from. I can store the remote IP and I know that there are localization services that map an IP to a geolocation.

How is this mapping done? Are there fixed tables, which IP address was given to which region?

Must I request the mapping in the moment of the access or can I request it days/months/years later? In other words: Is the mapping from IP to location fixed or does it change over time?

解决方案

The mapping from IP to location change over time. I have read that the databases change 5% each month, even though its hard to know if they really change that much or if the database providers lie to sell their updates more often. But its a fact that these databases change. So you should obtain the location of an IP address asap, at least not later that a month after you captured the IP address.
