DNSSEC adoption

Two different things, both worth knowing: whether a TLD is signed in the root, and how many of its registered domains are signed.

TLDs with zone data

A TLD being signed in the root says the registry supports DNSSEC. It says nothing about uptake: a signed TLD can have almost no signed registrations. The second column below is the one that measures actual adoption, and it needs zone data.

Data currency. Domain counts on this page are from zone files dated 19 September 2026 and refresh daily. Registrar figures are from ICANN's monthly registry reports for May 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
