DNS & Domain
4,519 of the 1,000,000 top sites in our Tranco top-1M census run NS1 (0.5%). A managed DNS provider offering authoritative DNS hosting and traffic-management features for domains. Detection is homepage-level HTML/header fingerprinting, so a site can run NS1 on other pages without it showing here.
