hosts
Name
hosts - enables serving zone data from a /etc/hosts
style file.
Description
The hosts plugin is useful for serving zones from a /etc/hosts file. It serves from a preloaded file that exists on disk. It checks the file for changes and updates the zones accordingly. This plugin only supports A, AAAA, and PTR records. The hosts plugin can be used with readily available hosts files that block access to advertising servers.
Syntax
hosts [FILE [ZONES...]] {
[INLINE]
fallthrough [ZONES...]
}
- FILE the hosts file to read and parse. If the path is relative the path from the root directive will be prepended to it. Defaults to /etc/hosts if omitted. We scan the file for changes every 5 seconds.
- ZONES zones it should be authoritative for. If empty, the zones from the configuration block are used.
- INLINE the hosts file contents inlined in Corefile. If there are any lines before fallthrough then all of them will be treated as the additional content for hosts file. The specified hosts file path will still be read but entries will be overrided.
fallthrough
If zone matches and no record can be generated, pass request to the next plugin. If [ZONES...] is omitted, then fallthrough happens for all zones for which the plugin is authoritative. If specific zones are listed (for examplein-addr.arpa
andip6.arpa
), then only queries for those zones will be subject to fallthrough.
Examples
Load /etc/hosts
file.
. {
hosts
}
Load example.hosts
file in the current directory.
hosts example.hosts
Load example.hosts file and only serve example.org and example.net from it and fall through to the next plugin if query doesn't match.
hosts example.hosts example.org example.net {
fallthrough
}
Load hosts file inlined in Corefile.
hosts example.hosts example.org {
10.0.0.1 example.org
fallthrough
}
