IP Validation?

fr600

I want to exclude 127.0.0.1 - 127.255.255.255 and 192.168.1.1 - 192.168.255.255 from viewing my site. Are there any easy way to do this, or any tutorial?

Thanks

127 addresses are loopback addresses meaning as soon as a request with that address hits the nic card its reversed back into the local system. 192 addresses are private internal nat addresses, so you are wanting to exclude all local users from potentially using your site? its not possible for a remote user to have these addresses.

Sorry I provided a bad example. I didn't actually mean only 127 and 192. There could be more like: 10.0.0.0 - 10.255.255.255 or 169.254.0.0 - 169.254.255.255

okay, well 10.* is also a reserved range, but to block the 169's if you are using apache you can make a .htaccess file with
deny from 169
in it, and all addresses beginning with 169 are blocked. or in your php scripts use

if (preg_match("/^169/", $_SERVER['REMOTE_ADDR'])) {
  echo "forbidden";
  exit;
}

but all scripts will have to have that.

It would be better to put these exclusions into your firewall rather than at the webserver / application layer.

.htaccess will do that also
