当用户运行托管 IIS 链接时，如何在 asp.net 中获取客户端 IP 地址

Question

I hosted my code in IIS,I want to get the user Ip when any user logged into my application using my hosted link. For example if 10 different users were accessed my link from 10 different systems means,I want to get all those 10 different IP address in asp.net c#. Is that same code will bring both server and IP address.I'm using Asp.net 4.5 -c#

Answer 1

Probably one of:

HttpContext.Current.Request.ServerVariables.Item("REMOTE_HOST")
HttpContext.Current.Request.ServerVariables.Item("REMOTE_ADDR")

Or...

HttpContext.Current.Request.ServerVariables.Item("X-Forwarded-For")

...if your server is behind a proxy. Be aware that the last one can be faked quite easily (and IPs are fakable/alterable too), so don't rely on it for anything related to security

Answer 2

You can get client IP by this code:

HttpContext.Current.Request.UserHostAddress

Answer 3

you can get your IP address like this:

var remoteIpAddress = request.HttpContext.Connection.RemoteIpAddress;
