127.0.0.0/8 is the loopback address. That means that any IP that

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.
I set DNS=127.0.0.1
No Joy. It was still random
# systemctl restart systemd-resolved.service
Then I tried DNS=127.0.0.1:53 and it is working
stable and fast, for now. I have thought I
had it working several times before, but got
my heart broken.
And now it is failing again.
It begs the question, if /etc/resolv.conf states
nameserver 127.0.0.53
why do I need to explicitly tell resolved what it
is in resolved.conf.
I think you're still missing the difference here. 127.0.0.53 is
systemd-resolved. Your bind is at 127.0.0.1. You need to tell resolved
to pass the requests to bind.
What does "resolvectl" show?
Then put the DNS entry back in the config and restart resolved and try
"resolvectl" again.
