1  0.0.0.0                                      * !u        * !u        * !u
--- Packet Response/Error Flags ---
(*) No response, (!N) ICMP network unreachable, (!H) ICMP host unreachable,
(!P) ICMP protocol unreachable, (!F) ICMP fragmentation needed,
(!S) ICMP source route failed, (!u) Transmit error, network unreachable,
(!f) Transmit error, fragmentation needed, (!t) General transmit error
