Ping operates by means of Internet Control Message Protocol (ICMP) packets. Pinging involves sending an ICMP echo request to the target host and waiting for an ICMP echo reply. The program reports errors, packet loss , and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard ...
With the normal untagged Ethernet frame overhead of 18 bytes and the 1500-byte payload, the Ethernet maximum frame size is 1518 bytes. If a 1500-byte IP packet is to be carried over a tagged Ethernet connection, the Ethernet frame maximum size needs to be 1522 bytes due to the larger size of an 802.1Q tagged frame.
The round-trip time or ping time is the time from the start of the transmission from the sending node until a response (for example an ACK packet or ping ICMP response) is received at the same node. It is affected by packet delivery time as well as the data processing delay , which depends on the load on the responding node.
Some commands are built into the command interpreter; others exist as external commands on disk. Over multiple generations, commands were added for additional functions. In Microsoft Windows, a command prompt window that uses many of the same commands, cmd.exe, can still be used.
A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.

The PathPing command is a command-line network utility included in Windows NT operating systems since Windows 2000 that combines the functionality of ping with that of tracert. [1] It is used to locate spots that have network latency and network loss. [2] [3]
The CTCP PING command works by sending an (often) integer argument (a timestamp) to a target client, the target client then responds by supplying exactly the same numerical parameter. The difference between the original timestamp and the current timestamp is calculated, with the result being displayed to the user that initiated the CTCP PING.
The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.
