Frequently asked questions
Which resolvers do you use?
Your browser queries Cloudflare's DNS-over-HTTPS resolver directly, so no data passes through our servers.
Why do I see cached answers?
Resolvers cache answers for the record's TTL. Lower your TTL before a planned change to speed it up.
Can I check a subdomain?
Yes, enter any hostname such as www, mail or a full subdomain.
