How to use the DNS Lookup
- Enter a domain (no https://).
- Pick a record type and click Lookup, or check all common records.
- Compare TTLs and values with your DNS provider.
About this tool
The Domain Name System translates names like example.com into IP addresses and holds the records that route email and prove domain ownership. When a site won't load after a migration, email bounces, or a verification TXT record “isn't found”, a DNS lookup is the first diagnostic step.
| Record | Purpose |
|---|---|
| A / AAAA | IPv4 / IPv6 address of the host |
| CNAME | Alias pointing to another name |
| MX | Mail servers, with priority |
| TXT | SPF, DKIM, DMARC, site verification |
| NS | Authoritative name servers |
| CAA | Which CAs may issue TLS certificates |
Queries go directly from your browser to Google Public DNS over HTTPS. Results reflect what that resolver currently caches, so recently changed records may take up to the old TTL to update. See our How DNS works guide.
Frequently asked questions
Why don't I see my new record?
Resolvers cache records for the TTL period. Wait, or lower the TTL before future changes.
How do I check SPF or DMARC?
Look up TXT on the domain for SPF, and TXT on _dmarc.yourdomain.com for DMARC.
What does NXDOMAIN mean?
The domain doesn't exist in DNS — check spelling or registration.
