Hello, all

What does this mean?

Sending 5, 100-byte ICMP Echos to 100.73.54.225, timeout is 2 seconds
EEEEE
Success rate is 0 percent (0/5), , +5 errors

It means that the ping application encountered some sort of error for every ICMP echo request it tried to send to 100.73.54.225.

The precise meaning of that E will depend on the version of PING application and operating systems you're using.

Read the help or man page for that version of ping you're using.

If your ping client has a verbose mode use that to get more detail on the errors.

Either it's an error on local machine such as no route to destination or ARP failure (if on local subnet) or your machine received some sort of ICMP error reply from another device in the network path (eg administratively denied by ACL on a router or TTL expired due to a routing loop).  If it's a network error you can use a packet capture (Wireshark or tcpdump) to see exactly what that error is and which device sent it.
