With systemd-242 (-r1, -r2), the DHCP server's search domains are not applied anymore by the dhcp client. Simply check systemd-resolved --status. (Of course, UseDomain=yes has been configured.) Workaround: Downgrade to systemd-241. This bug is known: https://github.com/systemd/systemd/issues/12531 https://github.com/systemd/systemd/issues/11391#issuecomment-488780831 https://github.com/systemd/systemd/pull/12548 Patch available: https://github.com/systemd/systemd/commit/fe0e16db093a7da09fcb52a2bc7017197047443d It should probably simply be applied. (I've borrowed the above links from the according Arch Linux report: https://bugs.archlinux.org/task/62748.)
