+   The ``request-ixfr`` statement determines whether the local server, acting
+   as a secondary, requests incremental zone transfers from the given
+   remote server, a primary.
+
+   IXFR requests to servers that do not support IXFR automatically
+   fall back to AXFR. Therefore, there is no need to manually list which
+   servers support IXFR and which ones do not; the global default of
+   ``yes`` should always work. The purpose of the ``provide-ixfr`` and
+   ``request-ixfr`` statements is to make it possible to disable the use of
+   IXFR even when both primary and secondary claim to support it: for example, if
+   one of the servers is buggy and crashes or corrupts data when IXFR is
+   used.
+
+   It may also be set in the zone block; if set there, it overrides the global
+   or view setting for that zone. It may also be set in the
