<div>Hi all,</div>
<div>I have a question related with the contacting external servers. If my server receives an referral answer from an external server with 3 NS records but just 1 A additional record, what is the normal behaviour? is the server supposed to resolve all 3 nameservers or continues with the iterative process contacting the server that have the additional A record.</div>
<div> </div>
<div>For example:</div>
<div>Trying to resolve <a href="http://www.testing.server.com/">www.testing.server.com</a></div>
<div>When contacting "<a href="http://server.com">server.com</a>" nameserver I receive in the answer 3 NS and 1 A Additional record:</div>
<div><a href="http://testing.server.com">testing.server.com</a> NS <a href="http://ns1.testing.server.com">ns1.testing.server.com</a> </div>
<div>
<div><a href="http://testing.server.com">testing.server.com</a> NS <a href="http://ns2.testing.server.com">ns2.testing.server.com</a> </div></div>
<div>
<div><a href="http://testing.server.com">testing.server.com</a> NS <a href="http://ns3.testing.server.com">ns3.testing.server.com</a> </div></div>
<div><a href="http://ns1.testing.server.com">ns1.testing.server.com</a> A 192.123.123.23</div>
<div> </div>
<div>Thanks in advance.</div>
<div> </div>
<div>Kind Regards,</div>
