Also affects me.
I cannot believe that this is still set to low. This is yet another
case of the systemd circus-tools causing unexpected behavior for long-
time linux users.
This breaks local DNS resolution in my homelab. I should NOT have to do
a Google search to fix this, it should just work properly (like it used
to).
Fresh install of 18.04.2. Notice that systemd is incapable of giving me
a lookup on my local LAN:
#CORRECT WHEN SPECIFIED MANUALLY
david@server:~$ nslookup ansible-nas 10.0.1.1
Server: 10.0.1.1
Address: 10.0.1.1#53
Name: ansible-nas
Address: 10.0.1.37
#SYSTEMD-RESOLVD PROXY IS BROKEN
david@server:~$ nslookup ansible-nas
Server: 127.0.0.53
Address: 127.0.0.53#53
** server can't find ansible-nas: SERVFAIL
#AND YET IT CLAIMS IT'S USING MY ROUTERS DNS
david@server:~$ sudo systemd-resolve --status

Title:
systemd-resolved appends 127.0.0.53 to resolv.conf alongside existing
entries
Status in systemd package in Ubuntu:
Confirmed
Bug description:
systemd-resolved, or more precisely the hook script
/lib/systemd/system/systemd-resolved.service.d/resolvconf.conf, causes
resolvconf to add 127.0.0.53 to the set of nameservers in
/etc/resolv.conf alongside the other nameservers. That makes no sense
because systemd-resolved sets up 127.0.0.53 as a proxy for those other
nameservers. The effect is similar to bug 1624071 but for
applications doing their own DNS lookups. It breaks any DNSSEC
validation that systemd-resolved tries to do; applications will
failover to the other nameservers, bypassing validation failures. And
it makes failing queries take twice as long.
/etc/resolv.conf should have only 127.0.0.53 when systemd-resolved is
active.
