>However, as we know it, on a 64 bit environment, this returns ::1 from ASP.NET. While this has never been a factor so far, I was relying on that to recognize the incoming hit from the Web server in a load balancing environment. Anyone knows how to obtain the real IP of the server in ASP.NET?

Rather than "64 bit environment" I think you meant "ipv6 environment". The "::1" value you're getting back is the local loopback address, the ipv6 equivalent of the ipv4 127.0.0.1.
