δΊ 2012-3-6 10:23, Spain, Dr. Jeffry A. ει:
I tested this by capturing network traffic on a bind 9.9.0 recursive resolver.
The commands 'rndc flush' followed by 'dig @localhost funnygamesite.com'
resulted in the following:
1. A query to m.gtld-servers.net.
2. The same referral response that you got below.
3. A follow-up query 500 microseconds after the response to ns1.dnsbed.com.
4. Ns1.dnsbed.com then provided the answer (127.0.0.1).
Thus it appears that bind 9.9.0 is relying on the data in the Authority and
Additional sections of the first query for the addresses of funnygamesite.com's
authoritative name servers. It is not making any additional queries for the
addresses of those name servers. Jeff.
Thank you Spain for the helpful info.
That make the question clear.
Regards.
