Ping Me

On a network, if you want to know if something is alive and reachable, you ping it.

Ping is a computer command that sends a simple message to your intended target. A successful reply gives you some basic but useful information:

1. I’m alive
2. Here’s my address
3. Here’s how close I am to you

If the ping comes back as “unreachable,” then you also get some useful, if opaque, information:

1. You can’t get to me
2. I’m powered off
3. You’ve got the wrong name or address

Ping your friends. Ping your family. Ping your colleagues. Ping your customers. Ping your partners. 

Ping me.
