For those who want to try it at home:
ping 33333333
ping 55555555
I am sorry, two random Internet users in Korea and Germany, your IP addresses are simply special.

Best ping is 127.0.0.1
It always resolves!
Fun fact 127.0.0.1-127.255.255.254 is all localhost
Pretty insane that around 0.4% of all IPv4 addresses are wasted.
Wayyyyyy more than that is wasted.
Apple (and others) used to have an A class. I think they gave some of it back to the pool.
Try pinging 127.1 - it is the same, but shorter.
Just another tipp from someone who learned TCP/IP from reading the sources over three decades ago…
even shorter:
ping 0This is a special case. This resolves to 0.0.0.0, and technically cannot be routed. Some(!) systems use it as a kind of alias for all local network addresses, but it is not a given.
That resolves to 0.0.0.0 - rarely useful
But it’s shorter!
But it does not work by definition, it is non-routable. That some systems use it as an alias is a different issue.
Voodoo! I had no idea.
It’s all in the documentation. But people don’t read anymore.
Can you explain how/why its the same?
My instinct says its actually trying to reach 127.1.0.0 (which is still local host), but that’s an educated guess at best.
