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 was told in my previous question that I can use the databases provided by MaxMind to determine locations.
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.
So, I got their databases downloaded from their site. They are csv files and open up in Excel.
InetAddress ip = InetAddress.getLocalHost() 是我获取计算机 IP 的方式.从那里我做 String justIP = ip.getHostAddress()
InetAddress ip = InetAddress.getLocalHost() is how I get the IP of my computer. From there I do String justIP = ip.getHostAddress()
我的问题是:
justIP 解析为城市位置???My question is:
justIP to a city location using the DB I just downloaded ??? 其中一个文件包含三列.startIPNum、endIPNum 和 locID 我不知道这些是做什么的，但我猜 locID 映射到一个城市和国家在另一个文件中的位置.
One of the files has three columns. startIPNum, endIPNum and locID I do not know what these do but I guess locID maps to a city and country location in the other file.
