Can we create a reverse DNS lookup zone for a /17 network in infoblox

[#1]

what is the best way to create a reverse DNS lookup zone for a /17 network in infoblox. Infoblox only provides in the below options: /8 /16 /24 /25 /26 /27 /28 /29 /30 /31

The question you posed here is a DNS architecture question, it isn't related to reporting.  I would suggest you post your question in the "NIOS DNS DHCP IPAM" section instead of the reporting one, that way you are more likely to get the right resources looking at it.

By their nature, reverse zones are classful as opposed to directly supporting CIDR.  With that said, the underlying network size and the reverse zone do not have to match.  Many environments will consolidate their reverse zones at a /16 level rather than go as far down as a /24.  If you want to cover a certain /17, you would build the reverse for the /16 it would fall under.
