The change in behaviour was noted in CHANGES. 4534. [bug] Only set RD, RA and CD in QUERY responses. [RT #43879] In theory one could extend UPDATE to recurse where the UPDATE message is forwarded by a recursive server to the servers for the zone in which case RD and RA would have meaning. The same would apply to any other future opcode. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
