I would imagine the answer will be that they aren't required but would be helpful.<br><br>Since the parent .xx is delegating to the second-level domains, if you do glue for all four DNS servers you are preventing a remote DNS server from having to go to the servers for example.xx to get the A records for the DNS servers for otherexample.xx.<br>

Hi,<br>
<br>
In the following example, the authoritive server for<br>
zone .xx has configured the delegations of the zones example.xx<br>
and otherexample.xx:<br>
<br>
example.xx NS ns1.example.xx<br>
example.xx NS ns2.example.xx<br>
ns1.example.xx A 11.22.33.44<br>
ns2.example.xx A 11.22.33.55<br>
otherexample.xx NS ns3.example.xx<br>
otherexample.xx NS ns4.example.xx<br>
<br>
the bind report these messages:<br>
<br>
"ns3.example.xx has no SIBLING GLUE address records (A or AAAA)"<br>
"ns4.example.xx has no SIBLING GLUE address records (A or AAAA)"<br>
<br>
because the glue records are not configured in the zone .xx, for<br>
ns3.example.xx and ns4.example.xx<br>
<br>
Are these glue records requiered ?<br>
<br>
I understand that is not. Is this right ?<br>
<br>
