Zones list mask or wildcard

[Cathy Almond]

No - new zones added dynamically don't go into named.conf or any include 
files of named.conf (these I suspect are part of a default OS 
distribution default set-up that you've adopted, but include files are 
often used anyway).

They go into another file or database that named accesses at start-up 
and maintains thereafter.

See BIND 9.18 Administrator Reference Manual:

Controls the ability to add zones at runtime via rndc addzone.

If yes, then zones can be added at runtime via rndc addzone. The default 
is no.

Newly added zones’ configuration parameters are stored so that they can 
persist after the server is restarted. The configuration information is 
saved in a file called viewname.nzf (or, if named is compiled with 
liblmdb, in an LMDB database file called viewname.nzd). “viewname” is 
the name of the view, unless the view name contains characters that are 
incompatible with use as a file name, in which case a cryptographic hash 
of the view name is used instead.

Configurations for zones added at runtime are stored either in a 
new-zone file (NZF) or a new-zone database (NZD), depending on whether 
named was linked with liblmdb at compile time. See rndc - name server 
control utility for further details about rndc addzone.
