127.0.0.0/8 is the loopback address.  That means that any IP that begins with 127 is a valid loopback address.  The three 0's can each be any number from 0 through 255.


So the 127.0.0.53 was the bind guys being sneaky!

That's not bind.  systemd-resolved is on 127.0.0.53 and 127.0.0.54 on my system.  bind would most likely try to get 127.0.0.1 as you demonstrated in your other email.  If you want systemd-resolved to use your bind server instead of the dhcp offered one, then modify /etc/systemd/resolved.conf to set 127.0.0.1 as the primary DNS server.

Named/bind uses port 53

$ grep -i 53 /etc/services
domain          53/tcp     # name-domain server
domain          53/udp

Not sure what your point is here. Yes, they *all* use port 53, but on different IP addresses. By default, resolv.conf points to systemd-resolved, so you need to tell that to pass it on to bind.

Everything is commented out in my
     /etc/systemd/resolved.conf

Yes, so you need to uncomment the DNS line and edit it.
