Thanks for the diagnostic command. It works ok in my local network,
could it be something to do with the way you're configuring your
hostname? Perhaps it would help if you could explain how you're
configuring your system, or show a test case that demonstrates the
problem in a vanilla lxc container or similar, so we could reproduce
what you're seeing.
stirling:~$ name="$(hostnamectl | grep "Static hostname:" | cut -d: -f2 |
xargs)"
stirling:~$ nslookup "${name}"

Non-authoritative answer:

** Description changed:
Starting Ubuntu 16.10 resolution of LAN addresses fails. This name
resolution failure is evident in every post 16.0 Ubuntu & derivative
that I have tested. See below - which shows 16.04 resolves, 18.04 and
Pop!_OS 19.04 fail, and other distros - Fedora 31, openSUSE Leap 15.1,
and Debian GNU/Linux 10 (buster) - all resolve as expected.
