systemd systemd.dns-delegate 5 systemd.dns-delegate DNS Server Delegation Configuration /etc/systemd/dns-delegate.d/*.dns-delegate /run/systemd/dns-delegate.d/*.dns-delegate /usr/local/lib/systemd/dns-delegate.d/*.dns-delegate /usr/lib/systemd/dns-delegate.d/*.dns-delegate *.dns-delegate files may be used to delegate DNS lookups in specific domains to specific DNS servers. These files are read by systemd-resolved.service8. Each such file defines a combination of one or more DNS servers and one or more DNS domains. Each such definition synthesizes a DNS lookup scope that ensure lookups below the specified domains are sent to the specified DNS servers, possibly in addition to any per-interface scopes and the global scope that systemd-resolved maintains anyway. DNS= Takes one or more DNS server specifications, in the same syntax as the option of the same name in resolved.conf5. Domains= Takes one or more domain name specifications, in the same syntax as the option of the same name in resolved.conf5. DefaultRoute= Takes a boolean value, defaults to off. Controls whether this DNS server is a candidate for looking up records for which no better route exists. # /etc/systemd/dns-delegate.d/foobar.dns-delegate [Delegate] DNS=203.0.113.47 Domains=foobar.com This ensures lookups of foobar.com and any domains below it are directed to DNS server 203.0.113.47. systemd1 systemd-resolved.service8 resolved.conf5 resolvectl1
