How we check

We send seven DNS-over-HTTPS queries to Cloudflare's public resolver, one per record type.
DNSSEC shows as validated when the resolver sets the authenticated data flag on the A query.

What this check can't tell you

Answers come from Cloudflare's resolver (1.1.1.1) and may be cached for up to the record's TTL.
We show up to 50 records per type.

Questions

Why do I see a private IP address?: We show what your public DNS zone publishes. If it lists a private address, that is in the public record.
Can I stop my site from being checked?: Yes. The SupercheckBot page explains how to ask for an opt-out; we add your domain to a block list.
