Hi,

Would anyone know a way of getting the Class C of a domain/IP address in PHP?

the gethostbyname() functions will return the IP but is there another function to get the Class C address?

I would appreciate your help on this!!

Thanks

Class C is just the 3rd subset of the IP (I think) - 192.168.2

Can't you just chop the end off $_SERVER["REMOTE_ADDR"] ?

Unless I'm mistaken with regards to what Class C IP actually is, this will do it.

<?php

preg_match('/^(?P<class_c>[^\.]+.[^\.]+.[^\.]+)/', $_SERVER["REMOTE_ADDR"], $match);
    
echo $match['class_c'];
  
?>
