Free Online DNS Lookup Tool

A DNS lookup resolves a domain's A, AAAA, MX, TXT, NS and CNAME records in one query over DNS over HTTPS, returned from our server.

How to Use This Tool

  1. Enter a domain such as example.com — no protocol or path is needed.
  2. Press Check to query all record types over DNS over HTTPS on our server.
  3. Review the A and AAAA records to see where the domain resolves.
  4. Check MX for mail routing and TXT for SPF, DKIM and verification strings.
  5. Confirm NS lists the name servers you expect after any DNS or registrar change.

What Is a DNS Lookup?

The Domain Name System translates human-readable domain names into the addresses and routing information networks actually use. Each record type serves a purpose: A and AAAA map a name to IPv4 and IPv6 addresses, MX directs email to the right mail servers, TXT holds free-form strings used for verification and email-authentication policies such as SPF and DKIM, NS lists the authoritative name servers, and CNAME aliases one name to another.

We query a resolver over DNS over HTTPS on our server and return all six record types together. Running the lookup server-side avoids browser CORS limits and bypasses your operating system's DNS cache, so you see authoritative answers rather than possibly stale local entries. A domain only carries the records it needs, so empty sections are normal — many domains have no apex CNAME, and a domain that does not send mail has no MX records.

Use it to confirm a site points at the right server after a migration, to verify mail routing, or to check that an SPF or domain-verification TXT record is published correctly.

Frequently Asked Questions

What are the main record types?
A and AAAA map a name to IPv4 and IPv6 addresses, MX routes email, TXT holds verification and policy strings like SPF and DKIM, NS lists the authoritative name servers and CNAME aliases one name to another.
Why query over HTTPS?
DNS over HTTPS queries a resolver directly and bypasses your operating system's DNS cache, so you see authoritative answers rather than possibly stale local entries. We run the query server-side and return the records.
Why are some record types empty?
A domain only has the records it needs. Many domains have no CNAME at the apex, and a domain that does not send email may have no MX records, so empty sections are normal.
