public class CIDRUtils
extends Object
```
A utility class that provides address evaluation (network and broadcast) and in-range functionality for a given IP Address from a CIDR specification. This utility supports both IPv4 and IPv6 addresses.

IPv4 Example
10.77.12.11/18 would produce 10.77.0.0 for the networkAddress and 10.77.63.255 for the broadcastAddress.

IPv5 Example
435:23f::45:23/101 would produce 435:23f:0:0:0:0:0:0 for the networkAddress and 435:23f:0:0:0:0:7ff:ffff for the broadcastAddress.
