Example scripts for enriching cidr block data with numeric representations of cidr blocks

This project provides examples for enriching cidr block data to make it easier to query in MongoDB

Sample:

CIDR blocks inserted are: (Indexed on ipAddress - ascending)

192.168.100.14/22
192.168.100.14/16
192.168.100.14/24
192.168.100.14/4
192.168.100.13/28
192.168.100.14/16

Case-1

Searching for IP - 192.168.100.15 is not returning any. Expected result is 192.168.100.13/28 as this is smaller block (16 IPs) & contains IP=192.168.100.15

> db.subscriber.find({"ipAddress":{$regex:'^192.168.100.15.*'}}).sort({"ipAddress":1}).limit(1)

Case-2

Searching for IP - 192.168.101.14 is not returning any. Expected result is 192.168.100.14/22 as this is smaller block(1024 IPs) & contains IP=192.168.101.14

> db.subscriber.find({"ipAddress":{$regex:'^192.168.101.14.*'}}).sort({"ipAddress":1}).limit(1)
