NAME

DESCRIPTION

SYNTAX

file DBFILE [ZONES...]

• DBFILE the database file to read and parse. If the path is relative, the path from the root plugin will be prepended to it.
• ZONES zones it should be authoritative for. If empty, the zones from the configuration block are used.

If you want to round-robin A and AAAA responses look at the loadbalance plugin.

file DBFILE [ZONES... ] {
    reload DURATION
}

•

reload interval to perform a reload of the zone if the SOA version changes. Default is one minute. Value of 0 means to not scan for changes and reload. For example, 30s checks the zonefile every 30 seconds and reloads the zone when serial changes.

If you need outgoing zone transfers, take a look at the transfer plugin.

EXAMPLES

example.org {
    file db.example.org
    transfer {
        to * 10.240.1.1
    }
}

Where db.example.org would contain RRSets (https://tools.ietf.org/html/rfc7719#section-4 ⟨https://tools.ietf.org/html/rfc7719#section-4⟩) in the (text) presentation format from RFC 1035:

$ORIGIN example.org.
@    3600 IN    SOA sns.dns.icann.org. noc.dns.icann.org. 2017042745 7200 3600 1209600 3600
    3600 IN NS a.iana-servers.net.
    3600 IN NS b.iana-servers.net.
www     IN A     127.0.0.1
        IN AAAA  ::1

Or use a single zone file for multiple zones:

. {
    file example.org.signed example.org example.net
    transfer example.org example.net {
        to * 10.240.1.1
    }
}

Note that if you have a configuration like the following you may run into a problem of the origin not being correctly recognized:

. {
    file db.example.org
}

We omit the origin for the file db.example.org, so this references the zone in the server block, which, in this case, is the root zone. Any contents of db.example.org will then read with that origin set; this may or may not do what you want. It's better to be explicit here and specify the correct origin. This can be done in two ways:

. {
    file db.example.org example.org
}

Or

example.org {
    file db.example.org
}
