Blocking an IP range

How can I block an IP range in the .htninja file?

example: ip range 180.170.160.150 – 181.171.161.151

I have understand that there is a variable for a single range:

“// Whitelist all IPs from 1.1.1.1 to 1.1.1.255:
if ( preg_match( ‘/^1\.1\.1\.\d+$/’, $_SERVER[“REMOTE_ADDR”] ) ) {
return ‘ALLOW’; // whitelist
}”

and if I write BLOCK instead allow the range will be blocked, but how to this with a larger range?

You can convert your two IP addresses to a long integer with the ip2long PHP function, then compare the visitor’s IP to these 2 values:

<?php
/*

*/
$low = '3031081110'; // ip2long( '180.170.160.150' );
$high = '3047924119'; // ip2long( '181.171.161.151' );

if ( isset( $_SERVER["REMOTE_ADDR"] ) ) {
   $ip = ip2long( $_SERVER["REMOTE_ADDR"] );
   if ( $ip >= $low && $ip <= $high ) {
      return 'BLOCK'; // reject it
   }
}
