HttpServletRequest.getRemoteAddr returns the IP address from where the request originates. You can compare that with the list of approved addresses, and return an error (maybe 403 - SC_FORBIDDEN) if it's not in that list.

Of course, IP addresses are fairly easy to spoof, so if you want real security, you can't rely on the client's TCP/IP address.
