    Hello,
    255.255.255.255 is the universal broadcast IP: all machines with an IP address are supposed to respond to this address.
    Fortunately, routers (that's their job) block this address; otherwise, the global network would collapse.
    PS:
    Routers generally block all broadcast messages, directed or not.
    Phew.

        The address 0.0.0.0 (or simply 0) is the null address used when your PC tries to connect to the network.
        In short:
        1) your PC [0.0.0.0]: @255.255.255.255 hello, I would like an IP
        2) your router (DHCP server) [192.168.1.1]: @255.255.255.255 hello, I am 192.168.1.1 (IP of your router), I can give you one
        3) your PC [0.0.0.0]: @255.255.255.255 okay 192.168.1.1, give me one
        4) your router [192.168.1.1]: @255.255.255.255 your IP will be 192.168.1.20
        your PC now has the IP 192.168.1.20

        (for more details, look up DHCP)
