The UNIX ping command is a tiny UNIX network tool that allows you to test your network, that of your ISP or organization, remote servers, and network latency.
The ping command works by using the Internet Control Message Protocol (ICMP) - in particular by sending ECHO_REQUEST packets, and by utilizing its Time To Live (TTL), latency, and packet loss detection to measure round trip hops to a given internet-connected computer at either an IP address or domain name.
Muuss was also the author of several 3D/CAD apps at the time, as well as the UNIX utility ttcp which measures network throughput using TCP and UDP protocols.
The UNIX ping command lets you test network servers and latency.
ping is one of the oldest and simplest UNIX commands and is available in virtually all UNIX distributions, including macOS.
