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?
I recently had a performance issue with one of my collections.
On a whim (and thanks to this article), I decided to try compacting (as written in the official documentation).
This worked brilliantly. However, I'm now wondering how often I should do it.
Since compacting is not a completely online task (I can only do it on passive nodes), I can't decide to do it every night and forget about it.
