| When << '**HostName=** is unset' if is_quadlet else '**--hostname** is not used' >> and the container uses a private UTS namespace (default), Podman sets the hostname to the first 12 characters of the container ID. The container name assigned with << '**ContainerName=**' if is_quadlet else '**--name**' >> is not used unless *container_name_as_hostname=true* is set in `containers.conf`. | ||

| Podman network DNS registers the container name, not this hostname. See **[podman-network(1)](podman-network.1.md)**. |
