DNS Lookup – Free Online Tool
Our free DNS Lookup tool shows every public DNS record of a domain in one click. Enter a domain name and instantly see its A, AAAA, CNAME, MX, NS, TXT and SOA records — no software, no sign-up. It is the fastest way to confirm that a new website, email setup or domain transfer is configured correctly.
What is DNS Lookup?
DNS (Domain Name System) works like the phone book of the internet. People remember names such as example.com, while computers connect using IP addresses. DNS records are the instructions that tell the internet which server hosts your website, which server receives your email and which services are allowed to send mail for your domain.
A DNS lookup queries these records directly, so you can see exactly what the rest of the world sees when it looks up your domain — which is often different from what your hosting panel claims while changes are still propagating.
How to use the DNS Lookup
- Type or paste the domain name (for example example.com) into the input box.
- Click the submit button to run the lookup.
- Review the results grouped by record type: A, AAAA, CNAME, MX, NS, TXT and SOA.
- Compare the values with the settings provided by your host or email provider and fix anything that does not match.

DNS record types explained
- A record – maps a domain to an IPv4 address.
- AAAA record – maps a domain to an IPv6 address.
- CNAME – makes one name an alias of another, such as www pointing to the root domain.
- MX record – tells the internet which mail servers accept email for the domain.
- NS record – lists the authoritative nameservers for the domain.
- TXT record – holds text data used for SPF, DKIM, DMARC and domain verification.
- SOA record – stores administrative details such as the primary nameserver and serial number.
Frequently asked questions
How long does DNS propagation take?
Most changes appear within minutes to a few hours, but it can take up to 48 hours depending on the TTL value of the old record and the caching of internet providers.
Why do my DNS results differ from my hosting panel?
Your panel shows what you saved; a DNS lookup shows what is actually published. If they differ, the change may still be propagating or was saved at the wrong DNS provider.
Can I check subdomains?
Yes. Enter the full subdomain, such as mail.example.com or shop.example.com.
