What Is DNSSEC and How to Enable It for Your Domain

DNSSEC (Domain Name System Security Extensions) adds a layer of cryptographic signatures to your DNS, so visitors can trust that the answer they receive really came from you — and was not tampered with along the way. Think of it as a tamper-proof seal on your domain's directory listing.

Ordinary DNS was designed decades ago and does not verify where answers come from. That opens the door to "DNS spoofing", where an attacker feeds visitors a fake address and quietly sends them to a malicious copy of your site. DNSSEC closes that gap.

How DNSSEC works, in plain terms

When DNSSEC is on, each DNS answer is digitally signed. A resolver checking your domain can verify that signature against a public key. If the signature does not match — because someone altered the record — the answer is rejected. Visitors never reach the fake.

Do you actually need it?

• Higher-risk sites — stores, membership sites, anything handling logins or payments — benefit most.
• Brand-sensitive domains gain protection against impersonation.
• Small brochure sites are lower risk, but DNSSEC still does no harm.

How to enable DNSSEC

DNSSEC is enabled in two places that must agree: your DNS host signs the zone, and your registrar publishes a matching "DS record". Because the exact steps depend on where your domain and DNS are managed, the safest route is to let us set it up correctly:

1. Confirm your domain uses VernalWeb nameservers.
2. Open a support ticket and ask us to enable DNSSEC for your domain.
3. We generate the signed zone and publish the DS record at the registrar for you.

If your domain is registered elsewhere, you may need to copy a DS record we provide into that registrar's control panel — we will give you the exact values.

Frequently asked questions

Will DNSSEC slow my website down?

The extra verification is tiny and happens at the DNS level, not on your page loads. Visitors will not notice any difference in speed.

Can DNSSEC break my site if set up wrong?

A mismatch between the signed zone and the DS record can cause resolution failures, which is exactly why it is worth having us configure both halves together. Done correctly, it is safe.

Is DNSSEC the same as SSL?

No. SSL secures the connection between a browser and your server. DNSSEC secures the DNS lookup that happens before that connection. They protect different stages and work well together.
