I've read an issue recently with Mac OS where a problem can be caused with DNS
if AAAA records can be/are returned from an upstream server. The Mac can
automatically assume IPv6 even if it isn't available. This I believe is due to a
different interpretation of an RFC regarding returns of AAAA records. The end
result is immense delays in the system, even affecting other kit on the network.
As I have neither Mac boxes at home nor use IPv6 I only read through this report
for professional curiosity, which I'm afraid explains the vagueness. But it
sounds like it may be what you're experiencing.
Ah! Found a linky: http://apple.slashdot.org/article.pl?sid=10/05/04/2029255
Make of that what you will. My explanation above might not be accurate.
