Acerca de Cloudflare

webatla rastrea 67.335.921 sitios web activos que utilizan Cloudflare, 21.8% de todos los sitios que indexamos. Descargue la lista completa de sitios web que usan Cloudflare como una exportación JSONL diaria. Cada registro incluye el dominio, además de DNS, WHOIS, dirección IP, país de hosting y ranking global.

Cloudflare es una empresa estadounidense de cloud de conectividad, fundada en 2009, que se sitúa delante de un sitio web como proxy inverso: el tráfico de los visitantes se enruta a través de la red perimetral de Cloudflare, que abarca centros de datos en más de 300 ciudades de todo el mundo, antes de llegar al servidor de origen. Desde esa posición, Cloudflare ofrece una red de distribución de contenidos (CDN) con caché perimetral, DNS autoritativo, mitigación de ataques DDoS, un firewall de aplicaciones web (WAF), terminación TLS y gestión de bots. Su nivel gratuito, ampliamente adoptado, la activación en un clic mediante los servidores de nombres de un dominio, y sus cabeceras de respuesta características (como los campos server: cloudflare y cf-ray) la han convertido en una de las piezas de infraestructura más presentes en la web pública, razón precisamente por la que identificar a gran escala los sitios web que usan Cloudflare es un problema de detección nada trivial y no una simple consulta.

webatla mantiene un índice actualizado de forma continua de los sitios web que usan Cloudflare, construido enteramente a partir de señales en vivo (registros DNS, cabeceras de respuesta HTTP y huellas de IP/ASN vinculadas al espacio de direcciones de Cloudflare) en lugar de etiquetas autodeclaradas, de modo que un dominio solo aparece listado mientras la evidencia sigue siendo vigente. Como el proxy perimetral enmascara el origen real de un sitio, esta es una tarea de detección relevante por derecho propio, y el índice se recalcula a medida que los dominios se incorporan a la red o la abandonan. El dataset se puede exportar como un archivo JSONL diario con un registro estructurado por dominio, y en esta página hay disponible una vista previa gratuita antes de la exportación completa de pago.

Una lista actualizada de los sitios web que usan Cloudflare resulta valiosa precisamente porque la tecnología es invisible para un visitante casual, pero decisiva para quien vende, protege o analiza infraestructura web: los equipos de ventas y generación de leads buscan empresas según la infraestructura que utilizan, los analistas dimensionan el mercado de CDN y seguridad y comparan la cuota de Cloudflare frente a proveedores competidores, los investigadores de seguridad estudian la superficie de ataque y la configuración perimetral en poblaciones enteras de sitios, y las agencias o los inversores auditan una cartera o un objetivo de adquisición para ver cómo están alojadas y protegidas sus propiedades. Como el índice combina cada dominio con atributos estructurados de DNS, alojamiento y ranking, los sitios que usan Cloudflare se pueden filtrar, segmentar y enriquecer, y no solo contar, y como los datos son de nivel de dominio y se actualizan a diario, permiten tanto una estimación puntual del mercado como el seguimiento continuo de cómo evoluciona la adopción con el tiempo.

Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data.

Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above.
