DNS Lookup — Free DNS Records Checker

Look up DNS records for any domain in real time. Our free DNS lookup returns A, AAAA, MX, NS, TXT, and CNAME records — essential for debugging email, verifying nameserver changes, confirming DNS propagation worldwide, and auditing how a domain is wired up.

What a DNS lookup returns

A DNS lookup queries authoritative nameservers to retrieve a domain's records. A records map to IPv4, AAAA to IPv6, MX to mail servers, NS to nameservers, TXT to verification strings (SPF, DKIM, DMARC), and CNAME to aliases. Our tool returns every common type in one query.

When to use a DNS lookup tool

After moving hosts (verify propagation), debugging email delivery (check MX, SPF, DKIM, DMARC), setting up Google Workspace or Microsoft 365 (validate TXT verification), or auditing whether DNS changes have rolled out to public resolvers globally.

DNS lookup vs nslookup vs dig

nslookup and dig are command-line tools shipped with most operating systems. Our web DNS lookup returns the same data with a friendlier UI, queries multiple record types in one shot, and shows propagation hints — no terminal required.

Frequently Asked Questions

What does a DNS lookup return?

A, AAAA, MX, NS, TXT, and CNAME records for the queried domain — typically in under a second.

Is the DNS lookup tool free?

Yes — free, unlimited queries, no signup.

How long does DNS propagation take?

Typically 1–48 hours depending on the record's TTL. Use this DNS lookup tool to verify when changes have propagated to public resolvers worldwide.

Can I check MX records with this DNS lookup?

Yes — MX records are part of the standard output along with priority and target mail server.

How is DNS lookup different from WHOIS lookup?

DNS lookup reads live records served by nameservers. WHOIS reads registration records held by the registrar. Run our WHOIS lookup for ownership data.
