Network Manager, I believe, has some complex logic to ensure that 
restarting it does not terminate all remote connections. That could 
explain why you didn't see any effect.

Reboot a few times perhaps to ensure that fix indeed is working.

`systemctl disable named.service` will actually disable the BIND app 
(and vice versa). But 'mask' is stronger. Attempts to enable the app 
won't work and service won't be started as a dependency of another 
service, etc. If you ever wish to use BIND again in future, remember to 
'unmask' it first.

Fixing this has been on my TODO list for while now. Currently busy 
working on email server.

Unfortunately, that's what this means.

I don't know if dnsmasq can do this but if it can, then the one that is 
spawned by Network Manager can be configured using a little trick[1] 
(just note the configuration file and write your own configuration in 
there).

Thank you for the detailed reports you have been sending. I don't always 
get the time to get involved in them but I hope to as much as I can. 
Keep them coming.
