I want to divert from the current flame war to make my biennial
semi-serious reminder that it was at least theoretically possible to expand
the IPv4 address space rather than make a whole new protocol. That we did
not do so was a failure of imagination.

Everyone thinks they get numbers. Until they try to compute a netmask or
perform any other non-rote IP networking task. The people who get hex tend
to actually get numbers. Both ways. If you want to know for sure whether
the other person understood you, explain it in hex.
