DNS Lookup

Free, no account. Tell us where the result should go, type the code from the email, and the check runs.

What it checks

Addresses

A and AAAA records, and the CNAME of the www host.

And

Mail

MX records plus the SPF and DMARC text records that stop spoofing.

Also

Control

NS and SOA, which say who runs the zone, and CAA, which says who may issue certificates.

How to read the result

What to do with it

  • No SPF or DMARC record means anyone can send mail as your domain.
  • MX pointing at a provider tells you where the email lives.
  • A missing AAAA record is common and harmless; a missing A record is a site that is down.
The next step

When one page is not enough

These tools check one thing at a time. The free SEO audit crawls a whole site and emails a report with the findings in priority order, and the paid plans turn that report into a proposal with the money at stake.

Questions

About the dns lookup

What is a DNS record?

A line in the domain's zone that maps a name to an address, a mail server, a nameserver or a text value. Browsers, mail servers and certificate authorities all read them.

Why do results differ from my DNS provider?

Changes take time to reach every resolver. The lookup here is live from a public resolver and is cached for an hour.

Is the lookup private?

DNS records are public by design. Nothing about the lookup is kept except the result, for an hour.
