I have a small home network with dnsmasq running on a Raspberry Pi, it
was all working nicely with several systems running xubuntu using the
Pi DNS successfully.
I have just added a new laptop running xubuntu 17.04 and on that
system unqualified local domain name requests fail.
I.e. on an xubuntu 16.04 system:-
chris@backup:~$ host esprimo
esprimo.zbmc.eu has address 192.168.1.3
chris@backup:~$ host esprimo.zbmc.eu
esprimo.zbmc.eu has address 192.168.1.3
chris@backup:~$ host pi
pi.zbmc.eu has address 192.168.1.2
chris@backup:~$
... but on the new 17.04 system:-
chris$ host esprimo
Host esprimo not found: 2(SERVFAIL)
chris$ host esprimo.zbmc.eu
esprimo.zbmc.eu has address 192.168.1.3
chris$ host pi
Host pi not found: 2(SERVFAIL)
chris$
The only significant difference (DNS wise) that I can see between the
systems is that the 16.04 systems run the 'run by NetworkManager'
local dnsmasq whereas the new 17.04 system has its local DNS handled
by some part of systemd. On the 17.04 system /etc/resolv.conf is:-
chris$ more /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by
resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual
nameservers.
nameserver 127.0.0.53
chris$
... and "systemd-resolve --status" returns:-
chris$ systemd-resolve --status

Can anyone suggest what the problem might be? (... and a fix!)
