Free DNS Lookup.
Look up DNS records for any domain in seconds. Verify A/AAAA/CNAME/TXT/NS (and more), confirm TTL values, and spot misconfigurations before they turn into downtime.
DNS Lookup.
How does DNS Lookup work?
Just enter a domain name (e.g., example.com), select a record type, and click “Check”. Our tool queries DNS and returns the records it finds for that domain—along with helpful details like TTL (time-to-live). Results are displayed in a clean format so you can quickly confirm your configuration or troubleshoot issues.
What are DNS records?
DNS records are instructions stored in your domain’s DNS zone that tell the internet where to send traffic. Depending on the record type, DNS can map a domain to an IP address, point a subdomain to another hostname, verify domain ownership, route email, or define service endpoints.
Which DNS record should you check?
- A: Points a domain to an IPv4 address (common for websites)
- AAAA: Points a domain to an IPv6 address
- CNAME: Alias from one hostname to another (common for app integrations)
- MX: Routes email to the right mail server(s) for your domain (uses priority)
- TXT: Verification and security records (SPF/DKIM/DMARC, domain ownership)
- CAA: Limits which certificate authorities can issue SSL/TLS certificates for your domain
- NS: Nameservers responsible for the domain’s DNS
- SOA: Zone metadata (authority, timers)
- SPF: Lists which servers are allowed to send email for your domain (helps prevent spoofing)
- DKIM: Adds a cryptographic signature to outgoing email so receivers can verify it wasn’t altered
- DMARC: Tells receivers how to handle failed SPF/DKIM checks and where to send reports
- PTR: Reverse DNS—maps an IP address to a hostname (often used for email trust/deliverability)
- SRV: Service routing (used by some apps and protocols)

What does “No records found” mean?
It usually means that record type isn’t published for that domain/hostname—or you’re looking up the wrong hostname (for example, www vs the root domain).
What does “NXDOMAIN” mean in DNS results?
NXDOMAIN means the domain/hostname doesn’t exist in DNS (the authoritative DNS returned “non-existent domain”).
What does “SERVFAIL” mean?
SERVFAIL means your resolver couldn’t get a valid answer—often due to authoritative DNS issues (timeouts, broken delegation, or misconfigured nameservers).
Why can “ALL/ANY” lookups be incomplete or inconsistent?
“ANY” isn’t a reliable “show me everything” query—many DNS providers limit or change how they answer it for security and abuse prevention, so it may return partial results.
What’s the difference between authoritative vs recursive DNS answers?
Authoritative nameservers hold the real DNS records for a domain, while recursive resolvers fetch answers and may cache them—so results can vary depending on which resolver is queried.
I see a CNAME—why don’t I see an IP address?
A CNAME points to another hostname, not an IP. To find the final destination, look up the A/AAAA records of the CNAME target.
