Getting past proxy addresses can be difficult when calling the code from ASP.NET, since some proxies don't play by the rules. However, if you proxy servers play by the rules and pass on the IP address data they are forwarding the traffic for, you can use the following solution:

I believe the actual answer you are looking for is the second most popular one. It walks you through how to access X_FORWARDED_FOR, which should give you the original IP address, along with every forwarded IP address.

For X_FORWARDED_FOR i am getting null value

Solution 1

Try this

Dim sysHost As [String] = System.Net.Dns.GetHostName()
Dim sysIP As [String] = System.Net.Dns.GetHostEntry(sysHost).AddressList(0).ToString(>
