<p class="MsoNormal">Using edu.bs, which seems to be working, the name ub.edu.bs can be resolved. If one queries for the SOA at edu.bs, the negative answer is the right answer – showing the SOA record owned by bs.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Asking for the SOA for com.bs., the responses I see, from all three servers for bs., have an authority section pointing towards the NS set for com.bs. This makes little sense as, if there is no soa record for com.bs, It can’t have an ns
set.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It’s hard to tell remotely, but, you probably want to set up com.bs just like edu.bs. But that’s not very reliable advice, based on not knowing the full intentions nor the contents of the zone file.<o:p></o:p></p>

<p class="MsoNormal">The .COM.BS is an empty non-terminal with various child domains<br>
registered beneath. The "ns36.cdns.net" nameserver for .BS responds<br>
with NXDOMAIN to "com.bs" qname-minimised queries.<br>
<br>
This in turn can and does sometimes lead to NXDOMAIN inference for the<br>
child domains.<br>
<br>
This nameserver needs to be withdrawn and fixed before it is returned to<br>
service.<br>
