We re-classified 18 billion DNS TXT queries across ten full crawls (April 2025 - July 2026) and turned the SaaS verification-token census into a time series. Anthropic tokens grew 625x to 131,812 apexes. The Dan.com shutdown moved five million marketplace tokens. Microsoft 365's domain share is flat while Google's climbs. And across every major vendor, only 19-29% of token disappearances are deliberate cleanup - the rest is domain death. For SaaS analysts, security teams, and Internet measurement researchers.

We classified every TXT record from a 17 April 2026 DNS crawl — 840 GB of raw JSONL (56 GB after xz compression) — and built a vendor census from the verification tokens domains leak into DNS. 40.2 million unique apexes carry at least one tracked SaaS verification token. Google's 26.0 million-apex footprint is 3.4x Microsoft 365's 7.6 million. Domain marketplaces (AfterNic + dan.com + 4.cn + Aliyun + west.cn + 17ex + Sedo + DomainEasy) collectively touch 5.0 million apexes — more than Atlassian, Stripe, Adobe, Apple, and DocuSign verification tokens combined. Zoho's 1.23 million is the single largest non-Google, non-Microsoft SaaS verification footprint we measure. The TXT layer is the closest thing the public Internet has to a SaaS census.
