Is Request.ServerVariables["REMOTE_ADDR"] reliable enough?

Question

Currently I am using Request.ServerVariables["REMOTE_ADDR"] to get the IP from the client.

What guarantees I get when calling this Method. Or should I look in other ServerVariables as well?

Answer 1

Found some really neat information on retrieving the client's IP address here.

Essentially, you should probably also pay attention to the Request.ServerVariables("HTTP_X_FORWARDED_FOR") as well. This helps to identify the actual IP address if the end user is going through a proxy whereas the REMOTE_ADDR attribute would be the address of the proxy...unless it is an anonymous proxy in which case, you would still just get the proxy address.
