Who Moves the World's DNS: 15 Months of Delegation Flux, a One-Month Million-Domain Migration, and the Nameservers That Outlive Their Owners

We followed the NS delegation of every apex domain across nine full crawls, April 2025 - July 2026 (404 million apexes). 61% of the web kept the exact same nameservers for fifteen months; operator switching runs at 2.3% a month; and the biggest moves were corporate re-plumbs - GoDaddy consolidating 2.1 million NameFind domains onto Afternic, Namecheap shifting 1.1 million parked names to an undocumented platform in one month. Meanwhile 339,000 domains still delegate to the retired Dan.com. For DNS operators, security teams, and Internet measurement researchers.

Who Runs the World's DNS: GoDaddy Owns the Default, Cloudflare Owns the Choice, and 92% of Domains Have a Single Point of Failure

We pointed an NS-typed crawl at 301 million registry domains to ask who actually answers the first question of every web request. 277.6 million are delegated, and the answer is concentrated: registrar-bundled DNS runs nearly half the delegated web, GoDaddy leads at 18.9% as the default nobody chose, and Cloudflare follows at 13.9% as the operator everybody migrates to — more than every hyperscaler cloud combined. Beneath the leaderboard sits a quieter finding: 92.5% of delegated domains depend on a single DNS organization with no independent backup. Built from 151 million-plus apex NS records.
