+DDNS settings
+-------------
+
+The ddns settings reside in the ``ddns`` key of the *configuration dictionary*,
+which is a custom NetJSON extension not present in the original NetJSON RFC.
+
+The ``ddns`` key must contain a dictionary, the allowed keys are:
+
++---------------------+---------+
+| key name            |  type   |
++=====================+=========+
+| ``upd_privateip``   | boolean |
++---------------------+---------+
+| ``ddns_dateformat`` | string  |
++---------------------+---------+
+| ``ddns_rundir``     | string  |
++---------------------+---------+
+| ``ddns_logdir``     | string  |
++---------------------+---------+
+| ``ddns_loglines``   | integer |
++---------------------+---------+
+| ``use_curl``        | boolean |
++---------------------+---------+
+| ``providers``       |  list   |
++---------------------+---------+
+
+The ``providers`` key itself contains a list of dictionaries, the allowed keys are:
+
++---------------------+---------+
+| key name            |  type   |
++=====================+=========+
+| ``enabled``         | boolean |
++---------------------+---------+
+| ``interface``       | string  |
++---------------------+---------+
+| ``ip_source``       | string  |
++---------------------+---------+
+| ``lookup_host``     | string  |
++---------------------+---------+
+| ``domain``          | string  |
++---------------------+---------+
+| ``username``        | string  |
++---------------------+---------+
+| ``password``        | string  |
++---------------------+---------+
+| ``service_name``    | string  |
++---------------------+---------+
+| ``update_url``      | string  |
++---------------------+---------+
+| ``update_script``   | string  |
++---------------------+---------+
+| ``ip_network``      | string  |
++---------------------+---------+
+| ``ip_url``          | string  |
++---------------------+---------+
+| ``ip_interface``    | string  |
++---------------------+---------+
+| ``ip_script``       | string  |
++---------------------+---------+
+| ``use_syslog``      | integer |
++---------------------+---------+
+| ``use_logfile``     | boolean |
++---------------------+---------+
+
+The required keys are:
+
+* ``enabled``
+* ``interface``
+* ``ip_source``
+* ``lookup_host``
+* ``domain``
+* ``username``
+* ``password``
+
+For the function and meaning of each key consult the relevant
+`OpenWrt documentation about ddns directives <https://openwrt.org/docs/guide-user/base-system/ddns>`_.
