This packet is the equivalent of saying,…"Hello, are you there?"…The remote system responds to the ping request…by sending back an ICMP echo reply.…This is the equivalent of answering the question…with, "Yes, I am here."…When you receive a successful response to your ping request,…you know that network connectivity…between the two systems is working properly.…This is especially helpful,…if you're having connectivity issues,…and aren't sure where the issue resides.…For example, if you're trying to access a website,…and it's not responding, the issue…could be in a variety of places.…
