About DNS lookup

DNS (Domain Name System) is the directory of the internet — it maps human-readable domain names to the IP addresses, mail servers, and other infrastructure that actually run a website or service. Every domain publishes a set of records, and this tool retrieves them so you can verify they're configured correctly.

What each record type means

A: Maps the domain to an IPv4 address.
AAAA: Maps the domain to an IPv6 address.
MX: Mail exchange. Tells other mail servers where to deliver email for this domain.
TXT: Free-form text. Commonly used for SPF, DKIM, DMARC, and domain verification.
NS: Nameservers — the authoritative DNS servers for this domain.
CNAME: An alias pointing one domain at another.
CAA: Certificate Authority Authorization. Specifies which CAs may issue SSL certs for this domain.
