Back to the tool
  1. 01

    Enter a domain name

    Any domain. We query the authoritative nameservers directly.

  2. 02

    We fetch all DNS record types

    MX, A, AAAA, CNAME, TXT, and NS records retrieved in parallel.

  3. 03

    See your full DNS configuration

    Every record displayed with type, value, TTL, and priority where applicable.

Why this matters

DNS records control where your email goes and how your domain resolves. Misconfigured MX records mean lost emails. Missing TXT records mean failed authentication. When something breaks in your email setup, DNS is almost always the first place to check.

Got questions? We've got answers.

MX (Mail Exchange) records tell other servers where to deliver email for your domain. They point to your email provider (Gmail, Outlook, etc.) and include priority values that determine the order of delivery attempts.
