摘 要：Recent IETF proposals for the secure dynamic updatesin the DNS dictate that any DNS update requests arerestricted to the same zone as the requester. This limitsthe flexibility and applicability of many servers such asCA servers. In this paper we propose to use two morebits in the DNS header section to define the scope of thezones over which a dynamic update key has an updateaccess right. These bits are called scope control *** also describe how requests for dynamic updates canbe generated and processed in the resolver and the DNSservers using these scope control bits
