I have created a Business Management System which is to be used by retailers with or without multiple sites.
我创建了一个商业管理系统，供有或没有多个站点的零售商使用。
It is important that a logged in user identifies his/her location, or site, so that the system can perform site related tasks automatically.
登录用户识别他/她的位置或站点非常重要，这样系统就可以自动执行与站点相关的任务。
I currently have a database of locations which includes an IP Prefix field, when the user goes to the log in page it looks for the first 5 digits of the current IP address, then:
我目前有一个包含IP Prefix字段的位置数据库，当用户进入登录页面时，它会查找当前IP地址的前5位数字，然后：
- If start of current IP matches a stored record it assumes user is at that site.
- 如果当前IP的开始与存储的记录匹配，则假定用户在该站点。
- If no IP matches then it asks the user which site they're in and asks them to update the IP.
- 如果没有IP匹配则它会询问用户他们所在的站点并要求他们更新IP。
This basic, and manual check works when the sites are a fair distance away or are on different ISPs for certain, the update is usually only required after a router restart and I've been using the system myself for about 4 years with no issues... BUT... I am not confident with it, so my question is; is there a better solution?
当站点距离相当远或者在不同的ISP上时，这种基本和手动检查有效，通常只有在路由器重启后才需要更新，并且我自己使用系统大约4年没有问题。但是......我对它没有信心，所以我的问题是;有更好的解决方案吗？
I realise the IP address is probably not the way as the best that gives me is the location of their ISP, but that's not what I need.
我意识到IP地址可能不是最好的方式，它给我的是他们的ISP的位置，但这不是我需要的。
In case it matters I am using ASP.NET coding in VB
如果它很重要我在VB中使用ASP.NET编码
Also, should mention, I'm looking for desktop based application, not mobile.
另外，应该提一下，我正在寻找基于桌面的应用程序，而不是移动应用程序。

I think you are going to have to rely on user input for this one. It's impossible (or at least, very very difficult) to know whether a user is using a proxy or not, and if they are you have no way of knowing where they really are. This is right and proper; would you trust every website you access with that kind of information? I sure as hell wouldn't.
我认为你将不得不依赖这个用户输入。知道用户是否使用代理是不可能的（或者至少非常非常困难），如果他们是你无法知道他们到底在哪里。这是正确的;你会信任你使用这种信息访问的每个网站吗？我肯定不会。

You can't use the IP address to give you 100% reliable location data if your clients connect over the internet (they could be going through a proxy or as you said you might just get the ISP's IP address)
如果您的客户端通过互联网连接，则无法使用IP地址为您提供100％可靠的位置数据（它们可能通过代理或者您说可能只是获取ISP的IP地址）

No, of course it is not possible to reliably locate an user by IP Adress. That adress can be faked, so the base of your info is not reliable.
不，当然不可能通过IP地址可靠地定位用户。该地址可能是伪造的，因此您的信息基础不可靠。
