+Answer reordering
+-----------------
+Certain clients are "dumb" and always connect to first IP address or name found
+in a DNS answer received from resolver intead of picking randomly.
+As a workaround for such broken clients it is possible to randomize
+order of records in DNS answers sent by resolver:
+
+.. function:: reorder_RR([true | false])
+
+   :param boolean new_value: ``true`` to enable or ``false`` to disable randomization *(optional)*
+   :return: The (new) value of the option
+
+   If set, resolver will vary the order of resource records within RR sets.
+   It is disabled by default.
