There might be a better way to do this but I would just parse the string.

$ips = "30..39,50..59,20..25";
@array;
#while there are more ranges in the string
while($ips =~ s/(\d+)\.\.(\d+),?(.*)/$3/)
{
    #loop over the range
    for $num ($1 .. $2)
    {
    push @array, $num;
    }
}
for(@array)
{
    print $_ . " ";
}
print "\n";
#OUTPUT
#30 31 32 33 34 35 36 37 38 39 50 51 52 53 54 55 56 57 58 59 20 21 22 
+23 24 25
