>As Michel suggests oRequest.ServerVariables("REMOTE_ADDR") is what you need (not sure why he included the other code).

The computer name is also a useful one. When you run in a load balancing environment, where multiple Web servers are responding to the same application, if you look at the Hit table, assuming you have one in your application, it is very useful to know that a specific hit has been handled by a specific IIS server. This is better than logging the IP as it is more readable in that case. The IP of the user, has mentioned, is another usage.
