We have a problem that use dig 9.9 ,the delay is too large.
The default behavior of dig changed in 9.9 to always use EDNS and set the AD bit.
But I set +noedns +nodnssec +noadflag£¬we still get a large delay.The window version similarly is better.Using the +noedns +nodnssec +noadflag is very affective.
How can fix the problem in the ubantu

Yes, those are very large delays..

This may not be your problem, but the last time I saw a similar
pattern, it was due to a local recursive server which had no
working outgoing IPv6 route but thought that it did.  The long
delays were from trying the servers which had AAAA 
records listed over IPv6, timing out, and then falling back to
the IPv4 server addresses.

Is it possible that that could be a factor in your case?

The nameservers for the nameservers for qq.com are broken. They don't repond correctly to AAAA queries ns1.qq.com, ns2.qq.com, ns3.qq.com and ns4.qq.com. This causes delays when getting the next set of addresses to query, which are incorrectly included in the reported times. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
