    Lightbulb iProblem Array and looping Ip address,How?

    Greetings all.
    I have a program calculation ip address like this.
    public static void main(String[]args){
            int host=450;
            String sMask="255.255.254.0";
            String[] octet;
            String IpAddress="192.168.100.0";
            octet = IpAddress.split("\\.");
            int oct1=Integer.parseInt(octet[0]);
            int oct2=Integer.parseInt(octet[1]);
            int oct3=Integer.parseInt(octet[2]);
            int oct4=Integer.parseInt(octet[3]);
            int i;
            System.out.println("Ip Address \t \tSubnet Mask");
            for(i=oct4;i<host;i++){
                System.out.println(oct1+"."+oct2+"."+oct3+"."+i+"\t \t"+sMask);
            }
        }


    print out from this program

    Ip Address Subnet Mask
    192.168.100.0 255.255.254
    192.168.100.1 255.255.254
    192.168.100.2 255.255.254
    192.168.100.3 255.255.254
    until...
    192.168.100.449 255.255.254
    :laugh: I want this program,if ip address octet 4 value "192.168.100.255",then continuing this program,like this.

    next >
    192.168.101.0 255.255.254
    192.168.101.1 255.255.254
    192.168.101.2 255.255.254
    until ...
    192.168.101.193 and Finish.

    What the lack from my program?
