What is DNSSEC?

DNSSEC (Domain Name System Security Extensions) cryptographically signs DNS data so resolvers can verify it hasn't been tampered with.

DNSSEC (Domain Name System Security Extensions) is a set of protocols that add cryptographic signatures to DNS records. Those signatures let resolvers verify that the answer they received is authentic and hasn't been altered in transit — protecting against attacks like cache poisoning.

The .best registry operates DNSSEC-signed zones, so names in the namespace can be validated end to end.
