Just build your own function to increment theid's. Won't have to worry about any out of bounds issues then. 
use strict;

my $hex = "24d0e803adb7";

for (0..16) {
    $hex = inc_hex($hex);
    print $hex, "\n";
}

sub inc_hex {
    my @a = reverse map {hex} split '', $_[0];
    $a[my $i = 0]++;
    while ($a[$i] == 16) {
        $a[$i] = 0;
        $a[++$i]++;
    }
    return join '', map {sprintf "%x", $_} reverse @a;
}
