sorry, I did not give a explicit discription about my question. The question is
that in my opinion the RR "<FONT
color=#000000>ns3.wondns.com. 172800 IN A 113.105.171.124</FONT>"
should not be included in the 'com.' zone but in the wondns.com zone.
</FONT></DIV>
<DIV><FONT face=Verdana color=#000080 size=2> The
zq681.com zone is authorized to the servers ns3.wondns.com zone and
ns4.wondns.com. Well, at the time, one question is coming
---where should be the addresses of the two servers
stored? Maybe in the com zone or maybe in the wondns.com zone. It is known
that wondns.com zone is Authorized out to the two servers --ns1.wondns.com and
ns2.wondns.com, so the </FONT> <FONT color=#000080>RR "</FONT><FONT
color=#000000>ns3.wondns.com. 172800 IN A 113.105.171.124</FONT><FONT
color=#000080>" should exist in the wondns.com zone instead of the com zone.
However, I find that the RR exists in the com zone. I want to know whether the
RR should exist in the com zone.</FONT></DIV>

<DIV>I'm not sure I completely understand your question; but let me provide</DIV>
<DIV>a tentative answer.</DIV>
<DIV></DIV>
<DIV>It's my understanding that what you've found represents the main</DIV>
<DIV>purpose of the "additional" section in the DNS response message, an</DIV>
<DIV>optimization saving resolvers one step in the recursion process. So,</DIV>
<DIV>my answer to your question would be "yes", what bind 9.7.2 is doing is</DIV>
<DIV>correct.</DIV>
<DIV></DIV>
<DIV>If the NS-set in the root zone does not match the NS-set in the zone</DIV>
<DIV>itself, well, the problem is not with BIND but rather with the</DIV>
<DIV>configuration of the zone and it should be corrected at that level.</DIV>
<DIV></DIV>
<DIV>However, I might have misunderstood your question. Just let me know :-)</DIV>
<DIV></DIV>
<DIV>regards</DIV>

<DIV>> hi, all</DIV>
<DIV>></DIV>
<DIV>> I dig zq681.com @a.gtld-servers.net</DIV>
<DIV>> the result is the following:</DIV>
<DIV>> ;; QUESTION SECTION:</DIV>
<DIV>> ;zq681.com. IN A</DIV>
<DIV>></DIV>
<DIV>> ;; AUTHORITY SECTION:</DIV>
<DIV>> zq681.com. 172800 IN NS ns3.wondns.com.</DIV>
<DIV>> zq681.com. 172800 IN NS ns4.wondns.com.</DIV>
<DIV>></DIV>
<DIV>> ;; ADDITIONAL SECTION:</DIV>
<DIV>> ns3.wondns.com. 172800 IN A 113.105.171.124</DIV>
<DIV>> ns3.wondns.com. 172800 IN A 208.98.33.250</DIV>
<DIV>> ns3.wondns.com. 172800 IN A 208.98.33.251</DIV>
<DIV>> ns4.wondns.com. 172800 IN A 113.105.171.78</DIV>
<DIV>> ns4.wondns.com. 172800 IN A 208.98.33.252</DIV>
<DIV>> ns4.wondns.com. 172800 IN A 208.98.33.253</DIV>
<DIV>> and I find that the bind9.7.2-p2 recursor just believe that the authoritave</DIV>
<DIV>> nameserver have the addresses listing in additional section in response, and</DIV>
<DIV>> thus</DIV>
<DIV>> directly request zq681.com to one of the address. I want to know whether it</DIV>
<DIV>> is wrong for the recursor to accept the addresses. If it is allowed, why is</DIV>
<DIV>> there the records like "ns3.wondns.com. 172800 IN A 113.105.171.124" in</DIV>
<DIV>> com. zone and how to do this?</DIV>
