There are ways you can do that on IPv6.

A single /64 has more address space than the entire 32 bit IPv4 address
space, 4 billion times more.

So if you want to hide your IPv6 topology, put every host in a single /64,
via something like ISATAP + RFC7217 and RFC8981, tunneled over IPv4, or
something else that allows you to put all hosts in a single IPv6/64, like
EVPN.

An IPsec VPN concentrator is another example of something that can put
everybody in the same /64.
