Class CIDR

java.lang.Object

com.github.jlangch.venice.impl.util.cidr.CIDR

All Implemented Interfaces:

java.lang.Comparable<CIDR>

public class CIDR
extends java.lang.Object
implements java.lang.Comparable<CIDR>

A class that gets an IP range from CIDR specification. It supports both IPv4 and IPv6.

CIDR (Classless Inter-Domain Routing) block functions. Parses CIDR IP notations to IP address ranges. It supports both IPv4 and IPv6.

See: https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

CIDR tool: // https://www.ipaddressguide.com/cidr

Example:

    CIDR cidr = new CIDR("222.192.0.0/11");
    System.out.println(cidr.toString());
