<DIV><FONT face=Verdana size=2> </DIV>
<DIV>I dig zq681.com @a.gtld-servers.net</FONT></DIV>
<DIV>
<DIV>the result is the following:</DIV>

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