Just because your domain is public doesn't mean your DNS is public as well. You can use a cert signed by a public CA in a private network just fine so long as you're using the right DNS setup.

Except that a lot of places have .local (which is terrible, I know, but still lots of places have it), or .lan. A public CA won't create certs for those.
Just because your internal domain for your computers ends in .local does not mean your internal websites need to end in .local.

There's nothing preventing you from creating another DNS zone.
