        the DHCP Server config shows "one-lease-per-client true" but the client is getting more then on IP address

        option domain-name "discoverpc.net";
        option ldap-server code 95 = text;
        option domain-search-list code 119 = text;
        option arch code 93 = unsigned integer 16; # RFC4578
        option custom-lan-0 code 43 = string;

        default-lease-time 7200;
        max-lease-time 86400;
        log-facility local7;
        one-lease-per-client true;
        deny duplicates;
        ping-check true;
        update-conflict-detection false;
        authoritative;
