+        There are two request counters related to EDNS:
+        <quote>request.edns0</quote> and <quote>request.badednsver</quote>.
+        The latter is a counter of requests with unsupported EDNS version:
+        other than version 0 in the current implementation. Therefore, total
+        number of requests with EDNS is a sum of <quote>request.edns0</quote>
+        and <quote>request.badednsver</quote>.
