+If the \fIupdate-optimization\fR parameter is true for a given client,
+the server will attempt a DDNS update for that client each time the
+client renews its lease, rather than only attempting an update when it
+appears to be necessary.   This will allow the DNS to heal from
+database inconsistencies more easily, but the cost is that the DHCP
+server must do many more DDNS updates.   We do not recommend enabling
+this on large networks with the current DHCP server.   This option
+only affects the behaviour of the \fIinterim\fR DDNS update scheme,
+and has no effect on the \fIad-hoc\fI DDNS update scheme.
