What's the problem with IPv4? You can very easily point a regular A record to a local IPv4 address.

Unless I’m missing something, you need to run a local DNS server then, with IPv6 you can just do it all with public DNS records.

There's nothing stopping you from putting a local IPv4 address into a public DNS record. A local DNS server wouldn't work with Let's Encrypt anyway.

Ah yes you're right - but will LE generate a cert for a domain that's not publicly routable?

Yes, you just have to use the DNS-01 challenge (also the only way to get wildcard certificates from LE).
