Mobile-First Indexing: What It Means for You
Google indexes the mobile version of your site. If mobile is weaker than desktop, rankings suffer.
Read article →How it works
- Enter a domain name (for example
example.com). - The tool sends live DNS queries for each record type to public resolvers.
- It collects every answer returned, including multiple values per record type.
- You get each record grouped by type with its value and TTL, all from live DNS.
What it shows
- A records — the IPv4 addresses the domain points to.
- AAAA records — the IPv6 addresses, where configured.
- MX records — mail servers and their priority for receiving email.
- NS records — the authoritative name servers for the zone.
- TXT records — SPF, DKIM, DMARC and verification strings.
- CNAME records — aliases that point one name at another.
- SOA record — the start of authority, with serial and refresh values.
- SRV records — service location entries used by some applications.
Common use cases
- Verifying a migration — confirm A and NS records point to the new host after a move.
- Email troubleshooting — check MX, SPF and DKIM are present and correct.
- Validating verification — confirm a TXT record for Google, Microsoft or a CDN exists.
- Debugging propagation — see what the live record actually returns right now.
Example
Look up example.com and you might see two A records pointing to its CDN, an MX record routing mail to a provider, an SPF string in TXT, and the zone's authoritative NS records — everything you need to confirm the domain is wired up correctly.
Frequently asked questions
Is the DNS Records Lookup free?
Yes — completely free, with no signup and no usage limits. Query as many domains and record types as you like.
Why don't my recent DNS changes show up yet?
DNS changes take time to propagate based on the record's TTL and resolver caching. The tool reads live records, but a recently edited record may still be cached by some resolvers for minutes to hours.
What else can I check about a domain?
Use the WHOIS Lookup to see who registered the domain and when it expires, and the SSL Certificate Checker to verify the TLS certificate on the resolved host. For email-record fundamentals, see our technical SEO audit checklist.
