What is ping and how its works ?
- Ping is a basic Internet tool that allows a user to validate that a specific IP address exists and they also can be the accept requests.
- The act of using the ping utility or command. Ping is used diagnostically to ensure that a host computer we are trying to reach is actually operating. If, for example, the user will be unable to use the File Transfer Protocol (FTP) to send files to that host while they cannot ping a host.
- Using ping, we can also learn the number form of the IP address from the symbolic domain name.
- The process of transfer a message to all the members of a mailing list requesting an ACK (acknowledgment code).
- This is done before sending e-mail in order to confirm that all of the addresses are reachable.
Who was invented Ping ?
- The original PING command stood for “Packet Internet Groper”, and was a package of analytic utilities used by DARPA personnel to test the act of the ARPANET.
- However, the current Internet Ping command refers to a program was written by Mike Muuss in December, 1983, which has since become one of the most multipurpose and extensively used diagnostic tools on the Internet.
How Ping works ?
- The Internet Ping program works much like a sonar echo-location, sending a small packet of data containing an ICMP ECHO_REQUEST to a quantified computer, which then sends an ECHO_REPLY packet in arrival.
- The IP address 127.0.0.1 is set by convention to always indicate on the computer. Therefore, a ping to that address will always ping yourself and the delay should be very short. The most basic test of local communications to be provided.
