                Multiple DHCP servers can share a host reservation. Host identifiers, IP addresses, and delegated
                prefixes for a host must match in each DHCP server's configuration. If they are different, they are
                treated as different hosts. Otherwise, they are combined, and the DHCP servers sharing the host are
                displayed in one of the panels on this page. Client classes and DHCP options can differ in the
                configurations of the DHCP servers owning the host. If this is the case, the client classes and/or DHCP
                options are displayed individually for each server.

                    Stork attempted to find leases on the Kea servers, but some servers failed to respond or returned an
                    error in response to the control commands. The reservation usage status may not take into account
                    all matching leases because some of them may reside on the servers, which returned an error. Issues
