Perhaps you'd get somewhere by mapping them to a proper enumeration. Maybe this will help: 
my @range = map { unpack "N", pack "C4", split /\./ } qw(10.0.70.1 10.
+1.50.20);
print "@range\n"; # the numbers themselves
print $range[1]-$range[0]+1, "\n"; # how many addresses
for ($range[0]..$range[1]) {
  print join(".", unpack "C4", pack "N", $_), "\n";
}
