Was ist eine WHOIS-Abfrage?

WHOIS ist das öffentliche Verzeichnis darüber, wer einen Domainnamen oder einen IP-Adressblock besitzt. Eine Abfrage zeigt den Registrar, über den die Domain gekauft wurde, wann sie erstellt wurde und wann sie abläuft, ihre Nameserver, ihre Statuscodes und einen Abuse-Kontakt zum Melden von Spam oder Phishing. Bei IP-Adressen werden der Inhaber des Netzes, der Adressbereich und die regionale Internet-Registry (ARIN, RIPE NCC, APNIC, LACNIC oder AFRINIC) angezeigt, die ihn vergeben hat.

RDAP: das moderne WHOIS

Dieses Tool fragt das Registration Data Access Protocol (RDAP) ab, den strukturierten JSON-Nachfolger des alten textbasierten WHOIS-Protokolls. Den autoritativen Registry-Server für jede TLD bzw. jeden IP-Bereich ermitteln wir anhand der Bootstrap-Dateien der IANA, sodass die Ergebnisse direkt von der Quelle stammen. Für die wenigen länderspezifischen TLDs, die noch kein RDAP anbieten, greifen wir auf klassisches WHOIS über Port 43 zurück.

Warum ist der Name des Inhabers verborgen?

Seit Inkrafttreten der EU-DSGVO im Mai 2018 schwärzen Registrare standardmäßig die personenbezogenen Daten privater Domaininhaber, und viele bieten kostenlose Datenschutzdienste an, die dasselbe für Unternehmen tun. Um einen Domaininhaber zu kontaktieren, nutzen Sie das Kontaktformular des Registrars oder die angezeigte Abuse-Adresse. Mehr über WHOIS und Datenschutz (auf Englisch).

Häufig gestellte Fragen

Wie finde ich heraus, wann eine Domain abläuft?

Geben Sie sie oben ein; das Ablaufdatum und der Countdown kommen direkt von der Registry.

Wie prüfe ich, ob eine Domain noch frei ist?

Nutzen Sie den Domain-Verfügbarkeitscheck, der einen Namen gleichzeitig für beliebte Endungen prüft.
