¿Qué es una consulta WHOIS?

WHOIS es el directorio público que indica quién es el titular de un nombre de dominio o de un bloque de direcciones IP. Una consulta muestra el registrador con el que se compró el dominio, cuándo se creó y cuándo vence, sus servidores de nombres, sus códigos de estado y un contacto de abuso para denunciar spam o phishing. En el caso de las direcciones IP, muestra el titular de la red, el rango de direcciones y el registro regional de internet (ARIN, RIPE NCC, APNIC, LACNIC o AFRINIC) que lo asignó.

RDAP: el WHOIS moderno

Esta herramienta consulta el Registration Data Access Protocol (RDAP), el sucesor estructurado en JSON del antiguo protocolo WHOIS basado en texto. Localizamos el servidor autoritativo del registro de cada TLD o rango de IP a partir de los archivos de arranque (bootstrap) de la IANA, así que los resultados llegan directamente de la fuente. Para los pocos dominios de país que aún no ofrecen RDAP, recurrimos al WHOIS clásico por el puerto 43.

¿Por qué aparece oculto el nombre del titular?

Desde que el RGPD de la UE entró en vigor en mayo de 2018, los registradores ocultan por defecto los datos personales de los titulares particulares, y muchos ofrecen servicios de privacidad gratuitos que hacen lo mismo con las empresas. Para contactar con el titular de un dominio, usa el formulario de contacto del registrador o la dirección de abuso que se muestra. Más información sobre WHOIS y la privacidad (en inglés).
