DNS lookup for domain records, including A, AAAA, MX, TXT, CNAME, and NS. Choose a record type and review the returned values and TTLs.
DNS lookup retrieves records for a domain. DNS connects names such as tooloogle.com with addresses such as 104.21.x.x and stores other information used by web and email services.
Use this interface when you need to inspect records without running dig or nslookup in a terminal.
Enter the domain, with or without www., and choose a record type. Use All to request the listed common types, not every record that could exist in the zone.
The tool queries Google's public DNS-over-HTTPS resolver. Like dig @8.8.8.8, it shows that resolver's answer, which may be cached rather than a fresh response from the domain's authoritative server.
A: the IPv4 address(es) the domain points to.
AAAA: the IPv6 address(es) the domain points to.
CNAME: an alias for another domain (e.g. www.example.com aliased to example.com).
MX: mail-exchange servers; the addresses that receive email for the domain, with priorities.
TXT: free-form text records used for SPF, DKIM, DMARC, Google/Microsoft domain verification, and BIMI.
NS: authoritative nameservers for the domain.
SOA: start-of-authority record with serial number, refresh, retry, expire, and minimum TTL.
CAA: certificate-authority authorization; which CAs are allowed to issue TLS certs for this domain.
SRV: service location records (used by SIP, XMPP, Minecraft, Matrix, and other protocols).
PTR: reverse-DNS, mapping an IP back to a hostname.
Queries Google's public DNS-over-HTTPS resolver
"All records" mode requests the listed common record types
Shows TTL alongside each record (so you know how long it's cached)
Auto-strips http://, https://, and paths: check that the resulting domain is the one you intended
Highlights special TXT records: SPF, DKIM, DMARC, Google verification
One-click copy for any record value
Dark mode that follows your system preference
Type or paste a domain into the input (URLs and bare domains both work).
Select a record type (or leave on All for a full snapshot).
Click Lookup.
Results appear in a table with record value, TTL, and copy buttons.
Use the returned records when reviewing these configurations:
Email deliverability: verify SPF, DKIM, DMARC, and MX records when setting up SendGrid, Mailgun, Google Workspace, or Microsoft 365.
Domain migration: inspect the returned nameservers and A records. One resolver result does not confirm global propagation.
SSL / certificate issuance: check CAA records before Let's Encrypt or a commercial CA tries to issue.
Debugging: figure out why a site won't load, why email is bouncing, or why a subdomain isn't routing correctly.
Security audits: inspect TXT records for leaked verification tokens or stale configurations.
Domain reconnaissance: look up nameservers, mail exchangers, and SPF includes for a competitor or vendor.
Learning DNS: students and new engineers can see how every record type is structured.
Lookups are sent to Google's public DNS-over-HTTPS endpoint, dns.google/resolve. The resolver receives the query; it is not a local-only calculation.
A result may differ from an authoritative dig query because resolvers cache records. Compare the returned value and TTL when investigating a recent change.
An A record holds an IPv4 address (104.21.45.67). An AAAA record holds an IPv6 address (2606:4700::6810:2d43). Modern domains typically have both so they're reachable over either protocol.
dig sometimes show different results than this tool?DNS results are cached: each server respects the TTL set by the authoritative nameserver. If you've just changed a record, different resolvers may show old or new values until the TTL expires. This tool queries Google's public resolver. To compare answers, also query with dig @1.1.1.1 (Cloudflare) and dig @your-isp-resolver to compare.
SPF and DMARC policies and DKIM public keys are published through DNS TXT records for email authentication. SPF lists which servers are allowed to send mail "from" your domain. DKIM is a cryptographic signature attached to outgoing mail. DMARC tells receiving servers what to do if SPF or DKIM fail (reject, quarantine, or just report). Check these records when troubleshooting email authentication; they do not guarantee inbox delivery.
Time-To-Live, in seconds. The TTL tells caching resolvers how long they may reuse a record before re-querying. A TTL of 300 = 5 minutes; 3600 = 1 hour; 86400 = 1 day. Lower TTLs make DNS changes propagate faster but increase load on the authoritative server.
Yes: use the PTR record type and enter the IP. The tool handles the in-addr.arpa reversal automatically.
Those numbers are priorities. Lower = higher priority. Mail servers prefer the lowest-numbered MX and can fall back to higher numbers if it is unreachable. Equal priorities are load-balanced randomly.
No. DNS lookup needs a network request to the external resolver.
How to Use DNS Lookup - Check A, AAAA, MX and TXT Records
Type or paste the domain you want to check. Review the domain after any URL prefix or path is removed.
Select the record type you need, or All to request the listed common types.
Click Lookup. Review the returned values and TTLs, then copy the records you need.
Compare answers from other resolvers or the authoritative server when investigating a change. One lookup does not establish global propagation.
