These three types resolve to an existing A record. PTR is for reverse zones. It is
the opposite of an A record.
33.3 Starting the Name Server BIND

as the name server address for
localhost

/etc/resolv.conf
,
you normally already have a working name resolution without needing to know the
DNS of the provider. BIND carries out name resolution via the root name server, a
notably slower process. Normally, the DNS of the provider should be entered with its
IP address in the configuration file
/etc/named.conf
under
forwarders

effective and secure name resolution. If this works so far, the name server runs as a
pure caching-only name server. Only when you configure its own zones will it become
