Q: What is the loopback address for IPv6?
- 127.0.0.1
- 0000:0000:0000:0000:0000:0000:0000:0000
- 1000:0000:0000:0000:0000:0000:0000:0000
- 0000:0000:0000:0000:0000:0000:0000:0001
Explanation: In IPv6, the “::1” notation is used to denote the loopback address. It is analogous to the loopback address 127.0.0.1 in the IPv4 protocol. Communication to the IPv6 loopback address is often looped back internally inside the network stack without affecting the actual network. This address is used to test network connection on the local workstation, and the test is performed using the IPv6 loopback address.
