Need to check the DNS records for a domain? Our free DNS Lookup Tool instantly retrieves A, AAAA, MX, CNAME, TXT, NS, and SOA records for any domain — no install, no login, no waiting. Just type a domain and see exactly what's in DNS in seconds.

How to Look Up DNS Records

  1. Enter a domain name in the input field — for example, example.com. You don't need the https:// prefix.
  2. Click "Look Up DNS" to query live DNS records via Cloudflare's public DNS resolver.
  3. Review your results — each record type is shown in its own section: A, AAAA, MX, CNAME, TXT, NS, and SOA.
  4. Copy any record with the copy button next to each result, or copy the full report for sharing.
  5. Search another domain anytime — just clear the field and run a new lookup.

Frequently Asked Questions

What is a DNS lookup?

A DNS lookup queries the Domain Name System to retrieve the records associated with a domain name. DNS records control how a domain routes email, resolves to servers, proves domain ownership, and more. DNS lookups are used by system administrators, developers, marketers, and anyone troubleshooting email or website issues.


What DNS record types does this tool check?

This tool checks seven common record types: A (IPv4 address), AAAA (IPv6 address), MX (mail exchange, controls where email goes), CNAME (canonical name / alias), TXT (text records used for SPF, DKIM, and domain verification), NS (nameservers), and SOA (Start of Authority, zone metadata).

Why might my domain show no records for a type?

Not all domains have every record type configured. For example, a domain that doesn't send email may have no MX record. A domain without a subdomain alias won't have CNAME records at the root. This is normal — missing records just mean that record type isn't in use.


How current are the results?

Results come from Cloudflare's public DNS resolver (1.1.1.1), which reflects live DNS data. Because DNS has a TTL (time-to-live), very recent changes may not yet be visible if they haven't propagated. Full propagation typically takes between a few minutes and 48 hours depending on your registrar and TTL settings.


Can I look up DNS records for subdomains?

Yes — just enter the full subdomain (e.g., mail.example.com or shop.example.com) and the tool will return whatever records are set for that specific subdomain.


What is an MX record and why does it matter?

An MX (Mail Exchange) record tells sending mail servers where to deliver email for your domain. If your MX records are misconfigured or missing, email sent to your domain will fail or bounce. Checking MX records is a common first step when troubleshooting email deliverability problems.


What are TXT records used for?

TXT records store arbitrary text in DNS. They're most commonly used for email authentication (SPF and DKIM records), domain verification for services like Google Search Console, and security policies (DMARC). Checking TXT records helps you audit your email security configuration.


Is this the same as running nslookup or dig?

Yes — this tool performs the same lookups that the command-line tools nslookup and dig perform, but in your browser without any terminal required. It's ideal for non-technical users or anyone who needs a quick answer without opening a command line.
