Ping is also used for troubleshooting purposes to check that a host machine that the user is attempting to contact is up and running. Ping may be used by any
operating system (OS) that has networking capabilities, including most embedded network administration software.
For example, Windows users may use the command prompt screen (start/run/cmd) to retrieve the dot address for any given domain name, such as 205.245.172.72, by typing ping xxxxx.yyy, where xxxxx is the second-level domain name, such as 'whatis,' and yyy is the top-level domain name, such as 'com.'
