hosts

hosts enables serving zone data from a /etc/hosts style file.

The hosts middleware 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 middleware only supports A, AAAA, and PTR records. The hosts middleware can be used with readily available hosts files that block access to advertising servers.

Syntax

hosts [FILE [ZONES...]] {
    fallthrough
}

• 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
• ZONES zones it should be authoritative for. If empty, the zones from the configuration block are used.
• fallthrough If zone matches and no record can be generated, pass request to the next middleware.

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 middleware if query doesn't match.

hosts example.hosts example.org example.net {
    fallthrough
}
