The \fIupdate-static-leases\fR flag, if enabled, causes the DHCP
server to do DNS updates for clients even if those clients are being
-assigned their IP address using a \fIfixed-address\fR statement - that
-is, the client is being given a static assignment. It is not
-recommended because the DHCP server has no way to tell that the update
-has been done, and therefore will not delete the record when it is not
-in use. Also, the server must attempt the update each time the
-client renews its lease, which could have a significant performance
-impact in environments that place heavy demands on the DHCP server.
