Query a domain's DNS records
DNS is the system that maps a domain name to the servers behind it. Its records answer different questions: where the website lives, where email goes, and more. This tool queries a domain's A, AAAA, MX, TXT, NS, and CNAME records, which is invaluable when setting up a domain or diagnosing why something isn't resolving.
How to use it
- Enter a domain name.
- Choose the record type, or view the common ones.
- Read the records returned.
What the records mean
- A / AAAA point the domain to an IPv4 or IPv6 address.
- MX directs email to the right mail servers.
- TXT holds verification and policy records like SPF.
Questions people ask
Why don't my changes show yet? DNS records are cached for a time (their TTL), so updates can take a while to propagate everywhere.
Is my query stored? The lookup is performed to answer your request; the tool doesn't keep a record of it.
