Ping este un instrument de rețea care este folosit pentru a verifica dacă un anumit calculator poate fi accesat prin intermediul unei rețele de tip IP. Ping trimte mesaje ICMP “echo request” (în românește solicitare de răspuns) prin pachete adresate IP-ului/Hostu-lui ce trebuie  vizat și așteaptă răspunsul la acesta de tip ICMP “echo response”. Transmițând periodic astfel de pachete și calculând întârzierea cu care ajung răspunsurile, ping estimează timpul timpul mediu a traseului, precum și rata de pierdere a pachetelor dintre host-uri.

Sintaxa:

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
[-r count] [-s count] [[-j host-list] | [-k host-list]]

[-4] [-6] target_name
