What is the purpose of the command ping ::1?
- It tests the internal configuration of an IPv6 host.
- It tests the broadcast capability of all hosts on the subnet.
- It tests the multicast connectivity to all hosts on the subnet.
- It tests the reachability of the default gateway for the network.
Explanation:The address ::1 is an IPv6 loopback address. Using the command ping ::1 tests the internal IP stack to ensure that it is configured and functioning correctly. It does not test reachability to any external device, nor does it confirm that IPv6 addresses are properly configured on the host.
