The direct answer
DNSSEC validates the authenticity and integrity of DNS answers; it does not encrypt website traffic. During deployment or migration, check the signing and delegation chain to avoid mismatches between DS records and the new DNS setup.
DNSSEC validates the authenticity and integrity of DNS answers. It does not encrypt DNS content and is not a substitute for an HTTPS certificate or application security.
Check the complete support path
Confirm support for the extension, registrar and authoritative DNS provider. Signing is handled at the DNS provider, while the registrar relationship commonly includes publishing matching DS information in the parent zone. Enabling one dashboard switch does not prove that the full validation chain is working.
Use values for the current domain
DS and key information must match the domain and current provider configuration. Do not copy values from an old screenshot or another domain. Record the provider's current status and instructions before completing the corresponding registrar-side setup.
Plan DNSSEC separately during a migration
If an old DS record remains in the parent while the new DNS service does not provide matching signatures, validating resolvers can fail. Coordinate the old and new configuration using the provider's migration process instead of changing nameservers and hoping for the best.
Verify the outcome
- Compare the registrar and DNS-provider status.
- Check that queries establish a valid chain.
- Test the website and important subdomains.
- Assign responsibility for ongoing key and configuration maintenance.
Teams unfamiliar with signed-zone migration should confirm the process with their providers first. DNSSEC is a DNS-validation measure, not a search-ranking switch.
A common question
Can DNSSEC replace HTTPS?
No. DNSSEC validates DNS data, while HTTPS protects communication between the browser and the website.
