Whois (engl. „who is": wer ist) ist ein Protokoll, mit dem von einem verteilten Datenbanksystem Informationen zu Internet-Domains und IP-Adressen und deren Eigentümern abgefragt werden können. (Quelle: Wikipedia).
Net::Whois::Raw von Walery Studennikov ermittelt ungeparste whois-Informationen.
Beispiel: whois Abfrage .org
#!/usr/bin/perl use warnings; use strict; use Net::Whois::Raw; my ($dominfo,$whois_server) = whois('perl.org'); print "$whois_server\n"; print $dominfo , "\n";
Das Programm liefert folgende Ausgabe (Personendaten durch ... ersetzt):

Der deutsche Domain-Registrar Denic hat seine whois-Dienste durch eine vorgeschaltete Captcha-Abfrage gegen automatische Abfragen durch Skripte gesichert. ...
Die Kommandozeilen-Version der whois-Abfrage bleibt zwar erhalten, ist ab sofort jedoch auf die Domain-Informationen beschränkt, die für Fehlerbehebungen bei technischen Problemstellungen benötigt werden, beispielsweise Nameserver und technische Kontaktdaten. Domain-Inhaber-Daten können nur noch über den neuen Captcha-gesicherten Zugang des webbasierten whois abgefragt werden.
