So just relying on a > PowerDNS release to fix this problem seems unwise. Sure, but it is a minor issue overall. FORMERR is a lot better that what used to happen. Nameservers used to drop AAAA queries so you got timeouts when all the nameseservers were working instead of when some are working. > Users are experiencing this problem /now/ in the field, and more users > will be experiencing it as BIND is upgraded in more and more places. > Every single user relying on a Fedora 15 DNS server, for example, is > going to see occasional unnecessary DNS timeouts when trying to resolve > host names. Well complain to the owners of those zones.

The DNS has multiple nameservers so that when one is down you can ask another and be able to cache the answer. Here none of the nameservers are giving answers that can be cached. FORMERR, NOTIMP, REFUSED/timeout are per server not per query tuple <QNAME/QTYPE/QCLASS>. > jik -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
