Top websites: who runs their DNS and edge
The 1,000 highest-traffic websites, ranked by agreement across several public traffic and link lists, and the authoritative DNS provider of each site's domain and the CDN, WAF or cloud front door of the hostname people actually load.
Top 1,000 fully scanned (2026-10-17). Updated weekly; the totals use each site's latest result.
