DNS record check
A DNS check shows the records that point a domain at its servers: A and AAAA for the website, MX for email, TXT for SPF and verification, NS for who runs its DNS, CAA for who may issue its certificates, and CNAME for aliases. This one asks public DNS-over-HTTPS resolvers.
FAQ
DNS check: questions
Cloudflare’s public resolver over DNS-over-HTTPS, and Google Public DNS when Cloudflare does not answer. Both answer from their caches, so a record you changed a moment ago can show its old value until its TTL runs out.
Time to live: how many seconds a resolver may keep a record before it asks again. After you change a record, resolvers can serve the old one for up to that long.
A CNAME cannot sit beside other records, and the root of a domain always has its NS records, so the root uses A and AAAA records instead. CNAMEs belong on names such as www.
The resolver checked the DNSSEC signatures on the answers and they hold. If the domain is not signed, the check says so; that is common and not an error.
No. It only reads public DNS. To change a record, use the DNS settings wherever the domain’s NS records point.
