DNSSEC is not enabled

What it means

The zone for example.com is unsigned, so a resolver cannot tell your real DNS answers from forged ones. An attacker who can poison a cache can redirect your mail without touching your account.

How to fix it

Enable DNSSEC at your DNS host, then publish the DS record it gives you at your registrar. Most providers do both in a single click.

Check your own domain

This page describes the condition. To find out whether your domain has it, run the DNSSEC test or the full checkup, which examines every record at once.

Understand it properly

This page covers one condition. For the whole picture, DNSSEC, defined, or start at the Health Library.

Where this comes from

We judge this against RFC 4033 section 3. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.

Other DNSSEC conditions

• DNSSEC validation is failing
• Zone is signed but the parent has no DS record
