Joshua,
Try something like the following:
import java.net.InetAddress;
import java.io.PrintWriter;
String remoteHost = request.getRemoteHost();
InetAddress clientAddr = InetAddress.getByName(remoteHost);
String dQuad = clientAddr.getHostAddress();
// Do something with the dotted quad address e.g., only allow
// local network access
if (!dQuad.startsWith("192.168.")) {
PrintWriter out = response.getWriter();
response.setContentType("text/plain");
out.println("Go to hell " + dQuad);
}
Ideally, this would be done in a filter servlet. Even more ideally, you'd
do this sort of filtering at the firewall level as your firewall will be
much better at spotting IP spoofing.
Chris.
