Who is Accessing My WebService?

[VBAHole22]

I am trying to get the ip address of users hitting my web service. I have tried the following 2 constructs:

 

Context.Request.ServerVariables["remote_addr"];
Context.Request.UserHostAddress.ToString(); 

 

With no success. Sometimes I will get a real ip address. Usually the first time during the day that I try it but then after that all I get is 127.0.0.1

 

I have tested this from several different system with the same results.
