If you are doing web hosting, you can retrieve the ip address like:

var clientAddress = HttpContext.Current.Request.UserHostAddress;

Or if you do self-hosting, you can use this

object property;
Request.Properties.TryGetValue(typeof(RemoteEndpointMessageProperty).FullName, out property);
RemoteEndpointMessageProperty remoteProperty = property as RemoteEndpointMessageProperty;
