Who Runs the Web's Address Book: Cloudflare Leads DNS at 28%, Not 40% — and the Market Is Fragmenting
We mapped the DNS provider for 1.66 million domains by their delegated nameservers. Cloudflare leads at 28.3% — still 3.2x the next provider (GoDaddy, 8.9%), but well below the 40% we reported in early 2026. As LLMSE's index more than doubled, DNS de-concentrated across every tier: the top two providers now hold 37% (was 51%), the top ten 58% (was 73%). DNS remains markedly more fragmented than business email, and the long tail is overwhelmingly European and Asia-Pacific hosting and registrar brands.
