CIDRUtils

CIDRUtils is a Java library that enables you to get an IP range from CIDR specification. It supports both IPv4 and IPv6.

###IPv4 Example

CIDRUtils cidrUtils = new CIDRUtils("10.77.12.11/18");
String networkAddress = cidrUtils.getNetworkAddress();
String broadcastAddress = cidrUtils.getBroadcastAddress();

Evaluating the code above would produce 10.77.0.0 for the networkAddress and 10.77.63.255 for the broadcastAddress.

###IPv6 Example

CIDRUtils cidrUtils = new CIDRUtils("435:23f::45:23/101");
String networkAddress = cidrUtils.getNetworkAddress();
String broadcastAddress = cidrUtils.getBroadcastAddress();

Evaluating the code above 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.
