<WRAP info>
**NOTE:**  The data for these zones is kept locally, from a file or downloaded.

The data can be served to downstream clients, or used instead of the upstream (which saves a lookup to the upstream).

The first example has a copy of the root for local usage.

The second serves example.org authoritatively.  

  * **name "."** covers **all** queries.
  * **primary:** fetches with AXFR and IXFR, or url to zonefile.
  * **fallback-enabled:** has default no.  If enabled, unbound falls back to querying the internet as a resolver for this zone when lookups fail.
  * **for-downstream:** has default yes.  If enabled, unbound serves authority responses to downstream clients for this zone.
  * **for-upstream:** has default yes.  If enabled, unbound fetches data from this data collection for answering recursion queries.
  * **zonefile:** reads from file (and writes to it if you also download it).
