Just a caution. IP addresses can't be used to uniquely identify clients. NAT Firewalls and corporate proxies are everywhere, and hide many users behind a single IP.

Try:

Context.Request.UserHostAddress

Try this:

string ipAddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

Haven't tried it in a webMethod, but I use it in standard HttpRequests

The HttpContext is actually available inside the WebService base class, so just use Context.Request (or HttpContext.Current which also points to the current context) to get access to the members provided by the HttpRequest.
