Comment 21 for bug 1624320

Hi,

I just upgraded from Ubuntu 16.10 to 17.04 and observed the following systemd-resolve behaviour that might be related to this bug:

--> Any domain listed after the "search" keyword in /etc/resolv.conf stops being resolved by systemd-resolve.

respectively

--> Any domain listed as "DNS Domain:" when querying "systemd-resolve --status" stops being resolved by systemd-resolve

I confirmed with tcpdump that systemd-resolve will not query my local or any dnsserver for any subdomains for any domain listed under the "search" keyword.

Changing the domains after the search keyword in /erc/resolv.conf immediately changes which domains systemd-resolve will ignore and not resolve.

The search domain is normally automatically set in response to receiving an "option domain-name" from the local dhcp server and normally used to translate requests for www to e.g. www.localdomain.at if localdomain.at was the domain-name sent by the DHCP server.
