So ... it means that If I need to move to a new server , lets
suppose for maintenance.
I only need to change the server name ( `hostname` ) and all should
continue working?
Also:
"name in cert must match name used to connect"
Can you point those names for:
openssl commands while creating certs
mosquitto_sub client comand line flag while connecting.
btw , thanks for this ... you are helping me a lot.
Regards,
Leandro.

The relevant standards (IETF PKIX) are very complicated, but
the essence
is:
program asks to connect to a name
system might canonialize the name
system translates that to an address and connects
remote provides a certificate
validation requires that the certifiate be reachable from a
configured
trust anchor (which more or less translates to "server
cert's parent
certificate (CA) is in the list of configured CAs"
name in cert must match name used to connect
So no, you shouldn't need dns. You just have to make the
names match.
