In particular, when the request is `kres.type.A`, so an A record, it gives back `192.168.30.55` with a [time-to-live](https://en.wikipedia.org/wiki/Time_to_live) of 900 seconds. This means that every request that follows this policy will answer the same IP address. The secont line adds [a new policy rule](https://knot-resolver.readthedocs.io/en/stable/modules-policy.html#policy.add) to the resolver, which means that every subdomain of `internal.example.com` will resolve to 192.168.30.55.

Since kresd assumes data in the DNS wire format, as defined in [RFC 1035](https://tools.ietf.org/html/rfc1035), we use a couple of convenience functions (`kres.str2ip` and `todname`) so we can just type our IP addresses or domain names without any trouble. We can also, potentially, specify multiple subdomains to check with the `policy.todnames` function: Since kresd assumes data in the DNS wire format, as defined in [RFC 1035](https://tools.ietf.org/html/rfc1035), we use a couple of convenience functions (`kres.str2ip` and `todname`) so we can just type our IP addresses or domain names without any trouble.
