The update-static-leases statement

            update-static-leases flag;

            The  update-static-leases 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 fixed-address statement - that
            is, the client is being given a static assignment.   This can only
            work  with  the interim DNS update scheme.   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 perfor-
            mance impact in environments that place heavy demands on the  DHCP
            server.
