+The default TTL value if none is specified in a zone file or zone insertion
+using the dynamic configuration.

+.. WARNING::
+ As changing this value can result in differently parsed zone file(s),
+ the corresponding zone SOA serial(s) should be incremented before
+ reloading or commiting the configuration. Alternatively, setting
