How to capture IP of the user acting in Sharepoint

[pksa2]

I need to somehow capture IP address of the user acting in Sharepoint Portal Server 2003. I know that the user is well defined, but IP gives additional information that is required by the "client" i.g. the location.
Do you have any idea?

calling HttpContext.Current.Request.UserHostAddress would give you the IP address.
