How to organize local web services, without outside access, on a Raspberry Pi with CNC addresses?

Question

Django

In the process of learning Django, I came up with several ideas for web services for personal (home) use without access from the Internet.
I want to place them on the Raspberry Pi 4, so that they are accessible within the local network not by IP:port, but by CNC addresses. How can this be organized?

Answer 1

Add the required domains to /etc/hosts. Run services on port 80.

Answer 2

Expose them as a hidden service in Tor - you will get long, but quite usable onion addresses.
