Ask HN: List of Carrier-Grade-NATs (CGN/RFC1918) Used

I work on a zero trust overlay and we're having some debates about who uses what address space we should use, what others use etc. I know of a few solutions in the space using some ranges but I was wondering if there was a big long list of them somewhere of blocks known to be used.

I've been trying to "internet search" this but I've not found it yet. Any tips to find such a list, if it exists? Or just leave behind a comment on ones you know about - that'd help too. ;) TIA
