DNS Lookup

Free DNS lookup — check A, AAAA, MX, TXT, NS and CNAME records for any domain, plus SPF and DMARC email settings.

Results come from Google Public DNS. Recent changes can take up to the TTL shown to appear everywhere.

What is the DNS Lookup?

DNS (Domain Name System) translates domain names into IP addresses and stores records for email, verification and more. Cubestack queries Google Public DNS over HTTPS and shows the records for the domain and type you choose.

How to use it

  1. 1

    Enter a domain

    Type a domain such as example.com — a full web address works too.

  2. 2

    Pick a record type

    Keep All records, or choose A, AAAA, CNAME, MX, NS, TXT, SOA or CAA.

  3. 3

    Look up

    Review the records, their TTL and the SPF and DMARC checks.

  4. 4

    Download a backup

    Save the records as a zone file (to import into a DNS provider), CSV (for Excel) or JSON.

  • Eight record types

    A, AAAA, CNAME, MX, NS, TXT, SOA and CAA — one at a time or all at once.

  • Email checks

    Shows whether SPF and DMARC are set up, so mail isn't marked as spam.

    Results from Google Public DNS — what most of the internet sees.

Frequently asked questions

Why don't I see my new record?

DNS changes take time to propagate and cached records persist until their TTL expires.

What is an MX record?

It tells the internet which mail servers receive email for the domain.

Where do SPF and DMARC live?

In TXT records — SPF on the domain itself, DMARC at _dmarc.yourdomain.com.

How do I back up my DNS records?

Look up your domain with All records, then choose Zone file. Most providers, including Cloudflare, can import it. The backup covers the records of that exact name; look up important subdomains (like www or mail) separately.
