What Is a DNS Lookup?
A DNS lookup checks the Domain Name System records published for a domain. DNS connects human-readable domain names with the information browsers and other internet services use to locate websites, mail servers and other services. Use this free online DNS lookup tool to inspect the records returned by a public resolver.

- MX record: Identifies the mail servers that receive email for a domain.
- NS record: Lists name servers associated with a domain.

- CNAME record: Makes one hostname an alias of another canonical hostname.
DNS Lookup FAQs
Is this DNS lookup tool free?
Yes. NinaTools provides this DNS record lookup tool free to use. Queries are sent to Google Public DNS over HTTPS, so availability and response details depend on that public resolver.
Why does a DNS lookup return no records?
The domain may not publish the selected record type, the resolver may return no matching answers, or the response may be temporarily unavailable. Check the spelling and try another record type.
Does a DNS lookup show every DNS record for a domain?
No. This tool displays the records returned for the selected queries by the public DNS resolver. It does not perform an authoritative zone transfer and cannot guarantee a complete list of every record in a domain's DNS zone.
What is the difference between a DNS lookup and a DNS record checker?
The terms are often used for similar tasks. Both describe checking DNS information for a domain, such as its A, MX, NS, TXT or CNAME records. The results can differ depending on the record type and DNS resolver used.
