How much of each country's own namespace is hosted at home, mailed by a domestic operator and served by a domestic DNS provider? We measured all three layers for 78 national country-code TLDs plus .eu: 29 hosting crawls from April 2023 to September 2026, and 12 MX and 10 NS crawls from April 2025. Domestic hosting is not losing to foreign data centres but to the edge: the median share of a country's websites behind anycast front doors doubled from 11% to 23%, almost all of them run by US companies, while the home share of located websites barely moved. With US-headquartered operators gaining mail share in 76 countries and DNS share in 74, the index — a descriptive composite of domestic control, not a measure of sovereignty or resilience — fell in 70 of 78 countries in seventeen months, from a median of 42.1 to 38.1. Iran, the United States, Japan and Germany keep most of their namespaces at home; among the 30 largest, Mexico, Canada and India keep the least. For policymakers working on digital sovereignty, registries, hosting and DNS operators, and Internet measurement researchers.

Data centers are fighting over power, and Northern Virginia is the prize. We located every address behind the website record of every registrable domain in 29 crawls, April 2023 to September 2026 — by cloud region tag, geofeed, geoIP and 213 speed-of-light RTT measurements — and mapped it to a metro and a grid operator. Northern Virginia serves 3.6% of the world's websites, more than any country except the United States and Germany, and one in five of those we can place in the US. Its share has not grown: it fell for live sites, while its biggest tenant became a domain-for-sale marketplace. The fastest-growing place on the map is no place: 47% of websites now answer from anycast and CDN front doors, up from 31%. For energy and policy reporters, utility and grid analysts, cloud-resilience engineers and Internet measurement researchers.

We counted every IPv4 address behind the website record of every registrable domain in 29 full crawls of the DomainsProject corpus, April 2023 to September 2026. The web grew 71% (169.3M to 289.7M websites); the addresses it answers from grew 16% (10.9M to 12.7M). Half of all websites now answer from just 1,025 addresses, down from 3,908, and two GoDaddy addresses alone serve 23.9 million. But the concentration at the top is the parking layer: the live web still needs ~17,700 addresses to reach half its sites, while its middle is thinning — its dedicated-address share fell by a quarter and half the live web now sits on 11 networks, not 20. The annual physical-layer companion to the Internet Concentration Index, for network operators, courts and regulators weighing IP blocking, privacy engineers, and Internet measurement researchers.

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.
