DNS and Domain ToolsDNS lookup: A, MX, TXT, CNAME and more
Type a domain name and see its DNS records and how long they are kept (TTL).
What it does
The tool asks a public DNS resolver, Cloudflare (1.1.1.1) or Google Public DNS (8.8.8.8), for the records of the name you type, using DNS over HTTPS. You can choose one type of record or all common ones at once. The answers are shown in a table with their TTL, which is how long a resolver may keep the answer.
How it was tested
We compared the tool's answers with the nslookup command on a computer for name server (NS), mail (MX), CNAME and address (A) records, and between Cloudflare and Google: the sets of records were the same. TXT records are shown without the quote marks that the DNS adds around each piece.
What the status line means
- NOERROR with records: the name exists and has those records.
- NOERROR with no records: the name exists but has no record of that type. For example, a domain with no IPv6 address has no AAAA record.
- NXDOMAIN: the name does not exist at all.
- SERVFAIL: the resolver could not get a valid answer: a broken name server, a timeout or a failed DNSSEC check.
Privacy
The name you type is sent from your browser to Cloudflare or Google, according to your choice, and not to ShareYourGroup. Read the privacy policy of the resolver you choose if that matters to you.
Why does it differ from what my registrar shows?
Registrars show the records they hold. Resolvers show what they have in their cache, which can be older by up to the TTL.
Can I look up a subdomain?
Yes: type www.example.com or _dmarc.example.com.
