Hi,<div><br></div><div>Is it correct that the recursor will use the results from the root servers as opposed to the next level down, the gTLD servers? For instance: dig ns <a href="http://yahooapis.com">yahooapis.com</a> on my PowerDNS recursor:</div>
<div><br></div><div><div> <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> ns <a href="http://yahooapis.com">yahooapis.com</a></div><div>;; global options: printcmd</div><div>;; Got answer:</div>

</div><div><br></div><div>The root servers have ns7 whereas the gtld servers do not. So it's almost as if my pDNS implementation (pdns-recursor-3.1.5-1.el5.centos) is using the root server results as opposed to the gtld results. Is this what's happening? </div>
