there a way to create a single reverse zone for <a href="http://100.64.0.0/10" target="_blank">100.64.0.0/10</a>
in Auth Server?</blockquote>
<p>Reverse delegation is done on octet boundaries, so you'll need to
create 64.100.in-addr.arpa to 127.100.in-addr.arpa inclusive.</p>
<p>If you want to cheat, you could create 100.in-addr.arpa, or even
just in-addr.arpa, and rely on the fact that you'll never receive
queries for any reverse outside the ranges of interest.</p>
<p>Of course, <a href="http://100.64.0.0/10" target="_blank">100.64.0.0/10</a> is a private range which isn't
delegated, so your recursors will still need to be configured to
forward {64..127}.100.in-addr.arpa to your authoritative servers.</p>
