OK then. What nameserver daemon behaves like this?
various versions of IE cache either for 30 minutes or an hour irrespective of the times they get back from the resolver. see http://support.microsoft.com/default.aspx?kbid=263558 I believe gecko based browsers are guilty of this too (although to a lesser extent -- 10 minutes iirc).
Interesting that the article in question cites IE up to version 6.
Did they change this behavior in IE7?
Nope, IE7 pins DNS records for 30 minutes as well (it's configurable with the same registry key). Cheers, Bojan
