A user issues a ping 2001:db8:FACE:39::10 command and receives a response that includes a code of 3. What does this code represent?
- address unreachable
- network unreachable
- host unreachable
- protocol unreachable
| Explanation & Hint:
An ICMPv6 code of 3 in a ping response typically represents “address unreachable.” This code indicates that the destination address specified in the ping command is not reachable or is not available on the network. It means that the network is unable to forward the ICMPv6 Echo Request to the specified address, indicating that the target address might be down or there’s an issue with the routing to that address. |
