Posso vedere il nome del proprietario di un dominio?

Nella maggior parte dei casi no: dal GDPR in avanti i registrar mascherano i dati personali del titolare nelle risposte pubbliche, mostrando solo dati aggregati o del servizio di privacy.

La ricerca WHOIS avviene localmente nel browser?

No, questo strumento interroga il servizio RDAP ufficiale di ICANN per ottenere dati aggiornati in tempo reale: a differenza di altri tool del sito, richiede una richiesta esterna per funzionare.

Che differenza c'è tra WHOIS e RDAP?

RDAP è il protocollo più moderno che ha sostituito il tradizionale WHOIS, standardizzato da ICANN, con risposte strutturate e maggiore coerenza tra i diversi registrar.

Online Domain Whois — Registration, Expiration, and DNS Lookup

When to use a domain WHOIS lookup

This tool looks up a domain's public registration information — registrar, registration date, expiration, nameservers — via ICANN's official RDAP service.

When to use it

You want to know when a domain expires or who the registrar is before a purchase or renewal.
You need to check a domain's nameservers for technical or DNS configuration reasons.
You want to check whether a domain you're interested in is already registered, and for how long.

When NOT to use it

You expect to find the owner's personal details: since GDPR, most registrars mask the registrant's personal data in public WHOIS/RDAP responses.

Alternatives

Your registrar's control panel for detailed information about domains you own, including non-public data.
A dedicated DNS lookup service when you need to check specific records (A, MX, TXT) beyond nameservers.

Common mistakes

Expecting to see the domain owner's name: since GDPR, this data is almost always redacted in public responses.
Confusing the domain's expiration date with that of the hosting or SSL certificate, which are separate services often with different expiration dates.

Frequently asked questions about WHOIS lookups

In most cases, no: since GDPR, registrars mask the registrant's personal data in public responses, showing only aggregated data or the privacy service's details.

No, this tool queries ICANN's official RDAP service to get real-time, up-to-date data: unlike other tools on this site, it requires an external request to work.
