Public bug reported: 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.
