#6 fix 30 Minute script on 64-bit systems

According to this thread: https://sourceforge.net/projects/ipaudit/forums/forum/59302/topic/1570947

In the ParseNetRange() function, the constant ~0 is used, but the value of this depends on the processor precision.

The solution is simple. In ParseNetRange(), replace the line

$mask = 0; ($mask = ~0 >> $2) unless($2 > 31);

with this

$mask = 2**(32-$2) - 1;

here is the relative patch
