We followed every one of the 181.1 million domains that resolved in April 2023 across 26 DNS snapshots to June 2026, and did the same for a 246.8-million-domain 2025 cohort. The resolving web loses 13-15% of itself every year — a half-life of roughly five years — but the deaths are wildly unequal: Freenom's five TLDs went 99% extinct in the largest die-off ever recorded in the DNS, the cheap-promo gTLDs lose up to 95% of their web in three years, and Germany's .de keeps 84% alive. For registrars, investors, security teams, and anyone who links to anything.

The first edition of the Internet Concentration Index: a synthesis of four full-corpus, typed-DNS censuses of the same ~3-billion-name dataset, measuring who controls the Internet's core layers one domain at a time. DNS, email, cloud hosting and the CDN/proxy edge each have a different owner — GoDaddy, Google, Amazon and Cloudflare — no single company controls all four, the enterprise giant everyone names (Microsoft) is nearly invisible by domain count, and 92.5% of delegated domains sit on a single point of failure. For policymakers, security teams, and anyone who has watched one outage take down half the web.

We replayed 26 monthly snapshots of where the world's domains resolve — 38 months of A-record and geoIP data, Apr 2023 to Jun 2026 — counted one domain one vote across tens of millions of apexes per month. The expected story was de-Americanization and cloud consolidation. The data tells a stranger one: the geographic map barely moved. The United States hosted 45.9% of resolving domains in 2023 and 45.2% in 2026. The only line that climbed is the anycast bucket that hides where a domain truly lives, and the only provider that genuinely surged is Amazon, which tripled its footprint while its share of cloud spending fell. This is the first longitudinal post in the series.

We crossed two full-corpus DNS censuses of the same May 2026 crawl — the MX layer that names who runs each domain's mail, and the SPF/DMARC/MTA-STS/BIMI layer that says whether that mail is authenticated. Across 149.8 million mail-capable apex domains, email-authentication posture turns out to be inherited from the provider, not chosen by the owner: security gateways and Microsoft 365 run the credible anti-spoofing stack on 17–19% of their domains, while the four largest registrar-bundled hosts — IONOS, Hostinger, Namecheap, OVH — run it on under 1.2%, and the largest email category on the Internet stops spoofing on just 3.5% of its 46.7 million domains. The 9% that actually resist spoofing are not spread across the Internet; they cluster behind a handful of operators.

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.

We pointed an MX-typed crawl at 390 million registered domains to ask who actually handles the Internet's email. Only 38.7% can receive mail at all. Among those that can, Google Workspace leads Microsoft 365 by 1.4 to 1 (13.2% vs 9.4%) — the inverse of the enterprise market — yet both are dwarfed by registrar- and host-bundled email, which serves nearly a third of all mail-capable domains directly and most of the long tail besides. The result is a geographic map: Google owns the Americas and the developer world, Microsoft owns Northern Europe and the Commonwealth, and domestic hosts own their home ccTLDs. Built from 151 million apex MX records.

A CNAME record is a forwarding address — it names who actually serves a hostname. We pointed a CNAME-typed crawl at 1.86 billion names and found 297 million aliases. Of the 169 million that point outward, 41% land on site builders and managed hosts, 20% on domain-parking lots, and only 6% on CDNs — because Cloudflare, which fronts a quarter of the web, flattens its CNAMEs into A/AAAA and barely appears. The alias map is a rental map: the web is served by a short list of platforms, and the record type you query decides which half you can see.

On 28 March 2026 IPv6 crossed half of Google's traffic — the eyeball Internet reached the majority. We pointed an AAAA-typed crawl at 315 million registry domains to measure the other half of the question, and the content Internet looks nothing like it: only 20.4% of domains publish any IPv6 address, Cloudflare alone generates 44.7% of it, and 45% of all domain IPv6 is a CDN edge in front of an origin that may still be IPv4-only. Strip the CDNs and origin-native IPv6 falls to 11%. This is server-side IPv6, measured from 1.88 billion DNS answers.

We resolved the full DNS, MX, web-edge, and email-authentication stack of 500 Fortune 500 corporate domains against a May 2026 typed crawl. No single vendor owns enterprise DNS — 28% of the F500 still run their own. Proofpoint sits in front of 48% of mail-enabled inboxes. Akamai serves a third of the web edge. And the F500 enforce DMARC at 73% versus ~42% globally — yet MTA-STS reaches just 2.3%. This is the corporate Internet's plumbing, measured from the records themselves.

We queried the email-authentication TXT layer directly — _dmarc, _mta-sts, default._bimi, and apex SPF — across a May 2026 DNS crawl, using MX records as the denominator. Of 150,020,997 mail-capable apex domains, 71.3% publish SPF, 34.1% publish DMARC, but only 11.7% enforce DMARC and just 9.0% run the minimum credible SPF-plus-enforced-DMARC stack. Two-thirds of DMARC records sit at p=none. MTA-STS reaches 0.144% and BIMI 0.084%. And 45.7% of all DMARC reports flow to a single registrar's default configuration. This is the state of email authentication, measured from the records themselves.
