        !            15: is used to assign an address
        !            16: to a network interface and/or configure
        !            17: network interface parameters.
        !            18: .I Ifconfig
        !            19: must be used at boot time to define the network address
        !            20: of each interface present on a machine; it may also be used at
        !            21: a later time to redefine an interface's address. 
        !            22: For the Ethernet network, the network interface must be assigned with both
        !            23: Internet and Ethernet station addresses using this command.
