Quizplus · Accepted Answer

Packets that begin with an IP address starting with 127 are reserved for loopback testing, which means that they are limited to communicating within the host device only. Therefore, packets with an IP address starting with 127 cannot be used to test network connectivity. However, packets with an IP address starting with 127.0.0.1 can be used to test whether the network adapter installed on the host is working properly.
