Riga 25:
Ad ogni modo il comando '''whois''' da riga di comando consente di visualizzare le informazioni contenute nel registro di '''IANA''' (registro predefinito e corrispondente all'opzione '''-I'''). Per i domini di primo livello italiani il ''refer'' è '''whois.nic.it''' a cui si può inviare un'istanza attraverso l'opzione '''-h''' oppure, per ottenere maggiori informazioni, visitando il sito '''web-whois.nic.it''' attraverso web browser.
Il refer non va confuso con il ''Registrar''<ref>{{Cita web|url=https://www.nic.it/it/registrar|titolo=Registrar {{!}} Registro .it|sito=www.nic.it|accesso=2025-02-27}}</ref> che è un fornitore di servizi Internet che ha un contratto con il ''Registro''<ref>{{Cita web|url=https://www.nic.it/it/il-mondo-del-it/chi-siamo|titolo=Chi siamo {{!}} Registro .it|sito=www.nic.it|accesso=2025-02-27}}</ref>. Il Registro non si occupa, infatti, di registrare direttamente domini per conto degli utenti finali. In basso un esempio dell'implementazione del comando ''whois'' con google.com e google.it. Il registrar www.markmonitor.com rimanda ad un suo contact form per reperire le informazioni di contatto email dei consulenti tecnici di google.com. Mentre le informazioni di contatto email dei consulenti tecnici di google.it sono reperibili solo attraverso web browser visitando web-whois.nic.it.<syntaxhighlight lang="bash">
