For the record Apple's current iChat (the OS (10.6.7) is completely up to date) fails such a test. It will try IPv6 and not fallback to IPv4. End users shouldn't be seeing these sorts of errors.
Is that possibly a failure of the underlying resolver library? Do other applications on the same platform behave correctly?
It doesn't matter where in the system the fault is. It's all Apple components. If the application doesn't get and try all addresses it is broken. The nameservers have all addresses in their caches. MacOS's local cache have all addresses in it. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
