I am trying to fetch all IP lists with in CIDR range using JAVA. I got one sample code, but I am not sure it’s working fine for all scenarios or not. Using java.net package.

public static List<String> getIPsInCIDR(String cidrRange) {
        List<String> ips = new ArrayList<>();
        
        try {
            // Split the CIDR range into IP and prefix length
            String[] parts = cidrRange.split("/");
            String ip = parts[0];
            int prefix = Integer.parseInt(parts[1]);
            
            // Calculate the number of addresses in the range
            int numAddresses = (int) Math.pow(2, (32 - prefix));
            
            // Convert the IP address to a byte array
            byte[] ipBytes = InetAddress.getByName(ip).getAddress();
            
            // Convert the byte array to an integer
            int ipAddress = 0;
            for (byte b : ipBytes) {
                ipAddress = (ipAddress << 8) | (b & 0xFF);
            }
            
            // Generate the list of IP addresses within the range
            for (int i = 0; i < numAddresses; i++) {
                int currentIP = ipAddress + i;
                
                // Convert the integer back to a byte array
                byte[] currentIPBytes = new byte[4];
                for (int j = 3; j >= 0; j--) {
                    currentIPBytes[j] = (byte) (currentIP & 0xFF);
                    currentIP >>= 8;
                }
                
                // Create InetAddress object from the byte array
                InetAddress address = InetAddress.getByAddress(currentIPBytes);
                
                // Add IP address to the list
                ips.add(address.getHostAddress());
            }
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
        
        return ips;
    }

Could you please check this and confirm. I tried this is works fine
