NAME         top

       systemd.dns-delegate - DNS Server Delegation Configuration

SYNOPSIS         top

           /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

DESCRIPTION         top

       *.dns-delegate files may be used to delegate DNS lookups in
       specific domains to specific DNS servers. These files are read by
       systemd-resolved.service(8). 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.

[DELEGATE] SECTION OPTIONS         top

       DNS=
           Takes one or more DNS server specifications, in the same
           syntax as the option of the same name in resolved.conf(5).

           Added in version 258.

       Domains=
           Takes one or more domain name specifications, in the same
           syntax as the option of the same name in resolved.conf(5).

           Added in version 258.

       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.

           Added in version 258.

EXAMPLES         top

       Example 1.

           # /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.
