Dan array af ipadresser

Måske dette kan bruges:

Mja.. Resultatet jeg var ude efter var mere ala:

function CalcDefaultGateway($IPaddress, $Subnetmask)
{
  $IPaddress_Octets  = explode(".", $IPaddress);
    $Subnetmask_Octets = MaskbitsToOctets($Subnetmask);
  $Ting_Octets      = array();

  for ($A = 0; $A <= 3; $A++)
    $Ting_Octets[$A] = (int) $IPaddress_Octets[$A] & (int) $Subnetmask_Octets[$A];

  $Ting_Octets[3]++;

  return implode(".", $Ting_Octets);

}

function MaskbitsToOctets($number)
{
  $octets=array();
  for ($A = 0; $A <= 3; $A++){
    if (8>=$number){
      $octets[$A]=255;
      $number-=8;
    } elseif (0<$number) {
      $octets[$A]=bindec(substr(substr("11111111",0,$number)."00000000",0,8));
      $number=0;
    } else {
      $octets[$A]=0;
    }
  }
  return $octets;
}


$firstip = ip2long(CalcDefaultGateway($_POST[ip_segment], $_POST[ip_cidr]));
$lastip  = $firstip + pow(2, (32-$_POST[ip_cidr])) - 2;
   
for ($a = $firstip; $a <= $lastip; $a++)
$ip_octets_array[] = long2ip($a);
   
Det giver mig et array med ipnumre
