    option fqdn.no-client-update flag;
        When the client sends this, if it is true, it means the client \\
        will not attempt  to update its A record.
        When sent by the server to the client, it means that the client \\
        should not update its own A record.
     option fqdn.server-update flag;
        When  the  client  sends  this to the server, it is requesting that the server update its A record.   When sent by the
