DNS / WHOIS Lookup
Look up a domain's DNS records & WHOIS info.
Inspect any domain in seconds. The DNS tab resolves live A, AAAA, MX, NS, TXT, CNAME, SOA and CAA records via Cloudflare & Google public resolvers — perfect for checking mail setup, propagation and verification records. The WHOIS tab pulls registration data over RDAP: registrar, creation/expiry dates, status codes, nameservers and DNSSEC. Free, no sign-up, no API key.
How to use DNS / WHOIS Lookup
Pick a lookup type
In this free online DNS and WHOIS lookup tool, choose the DNS Records tab for live records or the WHOIS tab for domain registration data.
Enter the domain
Type any domain like example.com into the search box — no http prefix needed — to instantly query its DNS or WHOIS information.
Run the lookup
Click Lookup and the tool resolves records via Cloudflare and Google public resolvers, or pulls registration data over the modern RDAP protocol.
Read DNS records
Scan the A, AAAA, MX, NS, TXT, CNAME, SOA and CAA records grouped by type so you can verify website hosting, email setup and TXT verification.
Inspect WHOIS data
Review the registrar, creation and expiry dates, status codes, nameservers, DNSSEC and abuse contact to learn who owns the domain and when it lapses.
Copy the values
Use the one-click copy on any DNS value to grab an IP address, nameserver or TXT record instantly for your own configuration or documentation.
Frequently asked questions
What's the difference between DNS and WHOIS?
DNS records tell you how a domain works right now — where its website and email point, which nameservers it uses and what verification records exist. WHOIS (delivered here via RDAP) tells you about the domain's registration — who the registrar is, when it was created and expires, and its status codes.
Why are some WHOIS fields empty or redacted?
Most registrars hide registrant name, email and address for privacy (GDPR and WHOIS privacy services). We show every field the registry actually publishes — registrar, dates, statuses, nameservers and DNSSEC are almost always available, while personal contact details usually are not.
Why does a record type show 'No records found'?
That simply means the domain has no record of that type. For example, a domain with no email setup won't have MX records, and most apex domains have no CNAME. It's normal, not an error.
Does it need an API key or account?
No. The tool is completely free with no sign-up and no API key — DNS is resolved with public resolvers and WHOIS uses the open RDAP protocol over HTTPS. A light anti-abuse rate limit is the only cap.
Which WHOIS data is available for which domains?
Most gTLDs (.com, .net, .org, .io, .app…) and many ccTLDs publish full RDAP data. A few TLDs don't run a public RDAP endpoint yet — in that case the WHOIS tab will tell you no public data is available.
How do I check the DNS records of a domain online?
Enter the domain in the DNS Records tab and click Lookup — this free DNS lookup tool resolves the live A, AAAA, MX, NS, TXT, CNAME, SOA and CAA records via Cloudflare and Google public resolvers, so you can verify website, email and verification records in one place.
How do I find out who owns a domain and when it expires?
Use the WHOIS tab to run a free WHOIS lookup — it pulls RDAP registration data showing the registrar, creation and expiry dates, status codes, nameservers and DNSSEC. Personal registrant details are often redacted for privacy, but registrar and dates are almost always shown.
How do I check if my DNS changes have propagated?
Run a DNS lookup here after making a change — it queries live public resolvers (Cloudflare and Google), so you see the current records. If they still show the old value, propagation isn't complete; it can take from minutes up to the record's TTL (often a few hours) to update everywhere.
What are MX and TXT records used for?
MX records point to the mail servers that receive email for a domain, so they're essential for email delivery. TXT records hold verification and email-authentication values like SPF, DKIM and DMARC. Check both on the DNS tab when setting up or debugging email.
