THE .SI FIELD GUIDE
.si DNSSEC setup & practical checks
Learn how .si DNSSEC delegation works and avoid mismatched DS records.
The .si zone supports DNSSEC. Your DNS operator signs the zone and the registrar submits matching delegation information. A mismatch can break resolution rather than improve security.
What DNSSEC protects
DNSSEC lets validating resolvers check the authenticity and integrity of DNS answers. It does not encrypt website traffic, replace HTTPS, or prove that a website’s content is trustworthy. Treat it as one part of domain operations.
Coordinate both sides
Confirm your DNS host can sign the zone and your .si registrar can manage the required DS information. Follow the DNS host’s exact values. Keep a recovery plan and test after activating the parent delegation.
Moving DNS or changing keys
Coordinate signing and DS changes when changing nameservers or DNS keys. Register.si warns about expired signatures and a parent zone retaining delegation after DNSSEC is disabled. Review the official guidance before making a change to a production domain.
