<div dir="ltr"><div><div><div>What I am trying to achieve is this: <br><br>I am using BIND9 only for forwarding DNS requests to other DNS Servers. <br><br></div>I  want the entire hosts in the <br>network   : 173.252.110.0<br>
</div>with the host range: 173.252.110.1 - 173.252.110.254<br> with a total 254 addresses to be sent for reverse lookup say to DNS : 8.8.8.8, using a single zone configuration as shown below.<br> <br></div><div>Instead of having a zone file for each and every IP in the network, i want to use one zone file to have all the hosts  in the  network 173.252.110.0 to be forwarded to 8.8.8.8. <br>
</div><div>So when i do a dig -x 173.252.110.27 which is in the range of the specified network, i want  it be forwarded to only 8.8.8.8 <br><br></div><div>When i do  dig on a specific address, it gets resolved, but not through the configured DNS 8.8.8.8, but through default DNS 8.8.4.4.  I hope this explains the situation which i am trying to solve with a zone file delegation.<br>
