DNS lookup: A, MX, NS, TXT records
We ask Google and Cloudflare for the records and show whether the two agree.
Free, no signup, usually a few seconds.
You will see: A, AAAA, CNAME, MX, NS, TXT, SOA and CAA, plus SPF and DMARC for mail.
Common questions
I changed my DNS and still see the old value. Why?
DNS records are cached for their TTL, sometimes hours. Different A or AAAA answers from Google and Cloudflare are normal for a CDN or location-based DNS, and a different SOA record is normal when a domain uses more than one DNS provider. Neither means a change is still propagating. When other records (such as NS or TXT) differ, a change may still be propagating. When they agree and are still old, the change was not saved at your provider.
What is the difference between A and CNAME?
An A record points straight at an IP address. A CNAME points at another name, and that name points at the IP. The root of a domain cannot be a CNAME, which is why platforms give an IP for the root and a CNAME for www.
What are SPF and DMARC?
TXT records that tell mail servers who may send email from the domain. Without them, mail from the domain tends to land in spam, and someone else can forge it.
Is there a limit?
Up to 20 checks an hour from one connection, with no account. A result is kept for ten minutes, so checking the same address twice returns the saved one.
