A user issues a ping 2001:db8:FACE:39::10 command and receives a response that includes a code of 2 . What does this code represent?

  • port unreachable
  • host unreachable
  • protocol unreachable
  • network unreachable
    Answers Explanation & Hints:

    When a host or gateway receives a packet that it cannot deliver, it can use an ICMP Destination Unreachable message to notify the source that the destination or service is unreachable. The message will include a code that indicates why the packet could not be delivered. These are some of the Destination Unreachable codes for ICMPv4:

    0 : net unreachable
    1 : host unreachable
    2 : protocol unreachable
    3 : port unreachable
