* Mark Andrews:
Authoritative servers need a cache. Authoritative servers need to ask queries. The DNS protocol has evolved since RFC 1034 and RFC 1035 and authoritative servers need to translate named to addresses for their own use.
See RFC 1996, A Mechanism for Prompt Notification of Zone Changes (DNS NOTIFY).
Authoritative servers in typical configurations need a resolver (and with views, you might even need a very specific resolver). This does not mean that authoritative servers must be caches. It also does not mean that a resolver operated from the view which contains a particular authoritatively served zone picks up the correct data (in other words, there are configurations where the current BIND magic does not work). -- Florian Weimer <fweimer@bfk.de> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99
