How can i have IP address +10 for configure the host

Use StringSplit to split the IP address into its parts, then add ten to the last one ;)

$asSplit = StringSplit($IPAddress, ".")

$asSplit[4] += 1

$IPAddress = $asSplit[1] & "." & $asSplit[2] & "." & $asSplit[3] & "." & $asSplit[4]

As Mat said ;)

MsgBox(64, "IP Increment", _IP_Add("192.168.2.200", 10));

Func _IP_Add($s_IP = "192.168.2.200", $i = 10)

    Local $a_parts = StringSplit($s_IP, ".", 0);

    If (IsArray($a_parts) = 0 Or $a_parts[0] <> 4) Then Return SetError(1, 0, "");

    $a_parts[4] += $i;

    $s_IP = $a_parts[1] & "." & $a_parts[2] & "." & $a_parts[3] & "." & $a_parts[4];

    Return SetError(0, 0, $s_IP);

EndFunc ;==>_IP_Add

Just in case you need this, it adds it up properly, so '0.0.0.0 + 256' = '0.0.1.0'.

MsgBox(64, "IP Increment", _IP_Add("192.168.2.200", 60))

Func _IP_Add($s_IP, $i)
    Local $a_parts = StringSplit($s_IP, ".", 0)
    If Not IsArray($a_parts) Or $a_parts[0] <> 4 Then Return SetError(1, 0, "") ; Incorrect input.

    $a_parts[4] += $i

    For $n = 4 To 1 Step -1
        $a_parts[$n - 1] += Floor($a_parts[$n] / 256)
        $a_parts[$n] = Mod($a_parts[$n], 256)
    Next

    If $a_parts[0] <> 4 Then Return SetError(2, 0, "") ; Out of range.

    $s_IP = StringFormat("%.3s.%.3s.%.3s.%.3s", $a_parts[1], $a_parts[2], $a_parts[3], $a_parts[4])
    Return $s_IP
EndFunc ;==>_IP_Add
