DNS Lookup
Look up any domain's DNS records in one click.
This check runs through this site's own server, so it works for any public URL — no CORS or browser restrictions. Queries run via Cloudflare's public DNS-over-HTTPS resolver.
How to use the DNS Lookup
- 1 Enter a domain name.
- 2 Pick a record type, or choose "All common" to query A, AAAA, CNAME, MX, TXT and NS at once.
- 3 Review the name, type, TTL and data for each record returned.
Frequently asked questions
What does NXDOMAIN mean?
NXDOMAIN means the domain does not exist as far as DNS is concerned — it is not registered, has been deleted, or there is a typo. It is different from a domain that is registered but simply has no records of the type you queried.
Why do I see multiple MX or TXT records?
Multiple MX records are normal — each has a priority number, and mail is tried in order from lowest to highest. Multiple TXT records are also common, often used for SPF, DKIM, DMARC and domain-verification strings from different services.
What is TTL?
Time To Live, in seconds — how long resolvers are allowed to cache a record before re-querying. A lower TTL means changes propagate faster but generates more DNS traffic.
Why do results here differ from what I configured with my DNS provider?
DNS changes take time to propagate, and results can be served from a cached, not-yet-expired copy at the resolver used for this lookup. Give it up to your configured TTL (or up to 24–48 hours for some providers) before troubleshooting further.
