ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams (“pings”) have an IP and ICMP header, followed by a struct timeval and then an arbitrary number of “pad” bytes used to fill out the packet.
The ICMP protocol allows ping to send echo request messages and receive echo reply messages directly through the IP layer. This design lets ping bypass the need for port numbers, making it a fundamental tool for network diagnostics and troubleshooting.
