Sorry, but lookup was Avahi really is before posting anything else on this:
Start-point: https://en.wikipedia.org/wiki/Avahi_%28software%29

Avahi is NOT about addresses of a box, its about services (e.g. ssh, http,
ftp) running on this box, and announceing them via answering a broadcast.

What you have done is exactly what we others are exposing here as
uninformed and and ignorant by those in charge.

Do you really want to show yourself here in that light? - Just asking.
