or recursive query<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>With a static-stub zone, you would get an iterative query. Forwarding
always results in a recursive query.</DIV>
<DIV><BR></DIV>
<DIV>How are you determining that your server is sending an iterative
query?</DIV>
<DIV><BR></DIV>
<DIV>Can we (the list) see your named.conf?</DIV>

<DIV><FONT face=Arial size=2><SPAN class=410301012-03052011>from the book

<DIV><FONT face=Arial size=2><SPAN class=410301012-03052011>I read that
the forward with the mode first sends a recursive query to the servers

with forward only it send an itérative query.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=410301012-03052011>So forward first
send an itérative or recursive query?</SPAN></FONT></DIV>
