You could use eval to create a new ip field and then use that instead:

 index=asa_db sourcetype=cisco:asa 
 | eval ip=if(cidrmatch("1.1.1.0/24",src_ip),"14.96.40.25",match("15.0.0.0/24",src_ip),"14.141.241.1",src_ip) 
 | iplocation ip 
 | geostats count by city

This eval is using cidrmatch to match the two cidr you gave and changing them to a known TATA communications IP address, which will then map to Bangalore or Delhi. If the regex doesn't match then it leaves ip equal to the src_ip.

The search assumes the field you want to use for the eval I s called src_ip, but it might be different in your data.

To find public ips in each location I just googled "ip addresses Bangalore" and found a website that said which IPs were in Bangalore.

To make it start with India as the default map edit the visualization and modify the "initial coordinates" to be latitude and longitude of central India.
