Thanks for the bug report, Romain. I cannot seem to be able to reproduce it here. Here's what I'm doing:
$ docker run --rm ubuntu:jammy /bin/sh -c 'apt update && apt install dnsutils -y && host -v non-existent-host-name' ... Trying "non-existent-host-name.localdomain" Trying "non-existent-host-name" Host non-existent-host-name not found: 3(NXDOMAIN) Received 115 bytes from 192.168.30.1#53 in 3 ms It's also working inside an lxd container (Jammy), and with debian:sid (both Docker and LXD containers).
