Configure systemd-resolved to use a specific DNS nameserver for a given domain

Use case


  • I use a VPN to connect to my work network
  • I'm on a Linux computer that uses systemd-resolved
  • I have a work domain called
  • is hosted by both public and private DNS nameservers

I need to

  • Resolve private hosts in when connected to VPN

(Note that this should also work for pointing DNS-blocked domains at different, non-blocked nameservers)


systemd-resolved now has the ability to specify nameservers for specific domains. Until recently this was not the case, systemd-resolved leaned on NetworkManager, which used dnsmasq for this purpose.

In your systemd-resolved config, which for me is at /etc/systemd/resolved.conf (Fedora), make sure you have this (assuming private nameservers are and

Specified domain names may optionally be prefixed with "~". In this case they do not define a search path, but preferably direct DNS queries for the indicated domains to the DNS servers configured with the system DNS= setting (see above), in case additional, suitable per-link DNS servers are known.

Restart systemd-resolved and you should be in business.
