How to use ip_intel lookup to perform a CIDR match ?

Hello Folks,
How can i perform a CIDR/Subnet match with the "ip_intel" lookup file that comes by default ?  This lookup KV store dataset has CIDR ranges and single IP's listed under "IP" column .

Basically if the Dest_IP from my search results fall in a subnet range of the "IP" column  of the lookup file , then it should display the result in a table format.  I am able to match against a single IP-address but not against CIDR  range.

How do you guys about this one ? Thanks in advance
