Dummie question on ping (loopback)
what's the point of having loopback when you can just ping your local ip address? for example if my ip is 1.1.1.1, why can't i just do ping 5 1.1.1.1 instead of ping 5 127.0.1.1? it seems to me the only point in having it is for the sake of convenience?

For ping, I think pinging both of them is the same (but why do you ever want to ping myself?)

But having an IP or 'localhost' alias hostname is always convenient, as those given dynamic addresses have a consistent way to refer to "myself".

Just my 20cents.
