ping is the name of a computer network tool used on TCP/IP networks (such as the

is reachable on the network from the testing host. It works by sending ICMP packets to
the target host and listening for replies
For example: if 192.168.1.2 is not existing while 192.168.123.100 exists. Users will
have the following results:
usr/config$ ping 192.168.1.2
PING 192.168.1.2: 56 data bytes
no answer from 192.168.1.2
usr/config$ ping 192.168.123.100
PING 192.168.123.100: 56 data bytes
64 bytes from 192.168.123.100: icmp_seq=0. time=5. ms
64 bytes from 192.168.123.100: icmp_seq=1. time=0. ms
