Was ist whois?

Whois ist ein Protokoll, mit dem Informationen zu IP-Adressen und Internet Domains abgefragt werden können. Es wurde in RFC 3912 definiert. Diese Informationen beeinhalten insbesondere Angaben zu den Eigentümern und Verantwortlichen.

Mitunter wird mit Betriebssystemen ein entsprechendes Kommandozeilen-basiertes Tool ausgeliefert. Die Nutzung erfolgt dann so:

  > whois 38.107.179.242

bzw. IP-basiert

  > whois 38.107.179.242
