I'm studying fragmentation on IPv6. I read about the fragmentation overlapping issue. Does anyone know if is possible, and if how to block this attack with ip6tables?

Smaller block size results in low internal fragmentation as compared larger block sizes. Is it possible to have more internal fragmentation with a smaller Block size as compared to a larger Block size if we are allowed to use typical block size values (multiple of 2) i.e. 512, 1024 or 2048 bytes?
If the block size of a file system is 4KB, then for a 1KB file, 3KB space(which is internal fragmentation) is wasted. So, under a directory, is there any command to summarize how much disk space is wasted due to internal fragmentation?
I just read this article about the virtually non-existent disk fragmentation on *nix filesystems.
It was mentioned that due to the way ext handles writing data to the disks, fragmentation may only begin manifesting on hard drives that are at least 80%, where the free space between the files starts to run out.
On how to deal with this fragmentation, the final paragraph reads:
