$this->network = long2ip(ip2long($this->ip) & ip2long($this->netmask));
$this->broadcast = long2ip(ip2long($this->ip) |
! (ip2long($this->netmask) ^ ip2long("255.255.255.255")));
return(TRUE);
}

}
$this->network = long2ip(ip2long($this->ip) & ip2long($this->netmask));
$this->broadcast = long2ip(ip2long($this->ip) |
! (~(ip2long($this->netmask))));
return(TRUE);
}

Reproduce code:
---------------
http://dev2.osuosl.org/~philips/ip/index.phps

Expected result:
----------------
Your network address: 192.168.1.0
Your netmask address: 255.255.255.128
Your broadcast address: 192.168.1.127

Actual result:
--------------
Your network address: 192.168.1.0
Your netmask address: 255.255.255.128
Your broadcast address: 255.255.255.138
