Top websites: who runs their DNS and edge
The 20 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 20 fully scanned (2026-10-17). Updated weekly; the totals use each site's latest result.
CDN & Security Market Share, Top 20
Each site counts once; a site split across providers is split evenly (DNS: by nameserver count).
