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.
New gTLDs
Legacy gTLDs
All gTLDs
Signed gTLDs
1,128
Unsigned
4
Second-level signing
1,100
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 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.
