What is PING?

PING stands for Packet Inter Network Groper and means “to get the attention of” or “to check for the presence of” another party online.

The ping command is a very common method for troubleshooting the accessibility of devices. It uses a series of Internet Control Message Protocol (ICMP) Echo messages to determine:

  • Whether a remote host is active or inactive.
  • The round-trip delay in communicating with the host.
  • Packet loss.

The ping command first sends an echo request packet to an address, then waits for a reply. The ping is successful only if:

  • the echo request gets to the destination, and
  • the destination is able to get an echo reply back to the source within a predetermined time called a timeout. The default value of this timeout is two seconds.


ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS] [-r count] [-s count] [[-j host-list] | [-k host-list]] [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

EXAMPLE : Go to command prompt and type command in below syntax and hit enter


This command will send four packets to the target IP address and recieve four packets as a reply on success, showing the presence and availabilty of device/machine with target IP address.
