I assume I'm affected by the same issue.
I also use my router (Mikrotik) to set up short aliases for hosts.
This works generally:
$ dig +short anton @10.0.0.1
10.0.0.12
In my /etc/resolv.conf, systemd-resolved is enabled:
$ tail -n 1 /etc/resolv.conf
nameserver 127.0.0.53
When running "systemd-resolve --status", I can see that the DNS server
is correctly set up for the interface via DHCP:
Link 4 (wlx0013ef8b0189)
Current Scopes: DNS
LLMNR setting: yes
MulticastDNS setting: no
DNSSEC setting: no
DNSSEC supported: no
DNS Servers: 10.0.0.1
However, it is not being used to resolve the shortnames:
$ dig +short anton @10.0.0.1
10.0.0.12
$ dig +short anton @127.0.0.53
<nothing>
$ dig +short anton
<nothing>

Title:
resolving short local hostnames doesn't work, fqdn are fine
Status in systemd package in Ubuntu:
Confirmed
Bug description:
Hi, I have a local "dummy" DNS server on my router which registers
DHCP clients with the hostnames that they have. But resolving these
hostnames doesn't work on zesty unless fqdn is used, otherwise there's
a timeout that says:
root@zesty:# host deckard
;; connection timed out; no servers could be reached
but
root@zesty:/mnt# host deckard.tyrell
deckard.tyrell has address 192.168.1.239
Yesterday I had a resolv.conf with "search tyrell" and shortnames
worked then, but today it's gone again. Besides right after a reboot
it fails like this:
u@zesty:~$ host deckard
Host deckard not found: 2(SERVFAIL)
and after restarting systemd-resolved I get the timeout.
