So if DNS Server X is configured against this zone<br>
, then any reverse DNS request for 173.252.110.0-173.252.110.255<br>
should be forwarded via DNS Server X<br>

Currently this is not the case. There is no forwarding in the above<br>
scenario ( where CIDR notation x.x.x.x/Mask is used)<br>

<br></div>
Neither the BIND nor DNS does use the CIDR format.<br>
the resursive resolution searches for 27.110.252.173.in-addr.arpa which does<br>
NOT belong into 0/24.110.252.173.in-addr.arpa, they are two separate names.<br>
<br>
You would have to set up either zone 27.110.252.173.in-addr.arpa or<br>
110.252.173.in-addr.arpa. <br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im">
Only when the zone file is changed to<br>
zone "110.252.173.in-addr.arpa" IN {<br>

All the requests for<br>
<br>
173.252.110.0-173.252.110.255 is forwarded to 10.10.96.1.<br>
</div></blockquote>
<br>
Use 110.252.173.in-addr.arpa then. You should be aware that the IP range<br>
belongs to facebook, as already noted.<span class="HOEnZb"><font color="#888888"><br>
