You can make a zone of however many labels you wish, but it's not
perfect in ONLY affecting that one label. For example, if your zone
was "a.test.example.com" you would also be authoritative for any
additional labels, such as "this.is.a.test.example.com." Those
wouldn't be resolved theough the regular authority for example.com
(or whatever subzone might be delegated.)
This is, however, a feature of dnsmasq. Simply list the name and
address in /etc/hosts and that name [only] is served out via DNS to
your local resolver clients.
