This package is used for converting IP range to CIDR(s).

1 IP range can have several CIDRs. For example, the IP range [192.168.1.0, 192.168.1.255] can be converted to [192.168.1.0/24]. [192.168.1.0, 192.168.1.254] can be converted to [192.168.1.0/25 192.168.1.128/26 192.168.1.192/27 192.168.1.224/28 192.168.1.240/29 192.168.1.248/30 192.168.1.252/31 192.168.1.254/32].

CIDR

Classless Inter-Domain Routing(CIDR) is a method of assigning IP addresses that improves the efficiency of address distribution and replaces the previous system based on Class A, Class B and Class C networks.

For example, CIDR 192.168.1.0/24 can represent the IP net whose IP range is from 192.168.1.0 to 192.168.1.255.
