Anything in your private network (even if it goes over public internet) should be encrypted and locked up anyway. Something like Wireguard or Nebula only needs a few (maybe just one) publicly accessible address. Inside the overlay network, it's easy to keep IP addresses stable.
Anything public-facing likely needs a DNS record, updatable quickly when the IP of a publicly accessible interface changes (infrequently).
