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.
