How do I use MaxMind's GeoIP database to determine location?
提问by Little Child
So, I was told in my previous question that I can use the databases provided by MaxMindto determine locations.
所以，我在上一个问题中被告知我可以使用MaxMind 提供的数据库来确定位置。
So, I got their databases downloaded from their site. They are csvfiles and open up in Excel.
所以，我从他们的网站下载了他们的数据库。它们是csv文件并在 Excel 中打开。
InetAddress ip = InetAddress.getLocalHost()is how I get the IP of my computer. From there I do String justIP = ip.getHostAddress()
InetAddress ip = InetAddress.getLocalHost()是我如何获得我的电脑的IP。从那里我做String justIP = ip.getHostAddress()
My question is:
我的问题是：
justIPto a city location using the DB I just downloaded ??? justIP使用我刚下载的数据库解析到城市位置？？？我对此很陌生，因此将不胜感激。
One of the files has three columns. startIPNum, endIPNumand locIDI do not know what these do but I guess locIDmaps to a city and country location in the other file.
其中一个文件具有三列。startIPNum，endIPNum而locID我不知道这些做的，但我想locID映射到另一个文件中的城市和国家的位置。
