The only way to get the internet IP address is to access a site that is outside your local network: i.e. on the internet.

If Request.ServerVariables is telling you that the IP address is 192.168.x.x then that is a good indication that both the server and the client are on the same local network (192.168.x.x is generally allocated by routers to internal computers).

If one or other of the server and client is outside the network, then the internet IP address is available.
