Ok, simple. The zone you want to forward is 110.252.173.in-addr.arpa.
There is no need to make it more complicated than that.
Good luck,

What I am trying to achieve is this:
I am using BIND9 only for forwarding DNS requests to other DNS Servers.
I want the entire hosts in the
network : 173.252.110.0
with the host range: 173.252.110.1 - 173.252.110.254
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.
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.
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
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.
I am not sure if the zone file configuration is correct.

It's not at all clear from your description what you're trying to
accomplish. Particularly it's not clear what you seem to be trying
to accomplish with the 2317 delegation for a /24 zone.
Can you describe what you're trying to do, and why? It may be easier
to help you that way. Please use the actual zone(s) you're working
with, as that will also make it easier.
