DNS Lookup

Query DNS records for any domain. Look up A, AAAA, MX, CNAME, TXT, and NS records to troubleshoot DNS issues or verify configuration.

Common Record Types

  • A - Maps domain to IPv4 address
  • AAAA - Maps domain to IPv6 address
  • MX - Mail server for the domain
  • CNAME - Alias pointing to another domain
  • TXT - Text data (SPF, DKIM, verification)
  • NS - Authoritative name servers

Frequently asked questions

What is DNS?

DNS (Domain Name System) translates human-readable domain names like 'google.com' into IP addresses that computers use to communicate. It's often called the 'phonebook of the internet'.

What is an A record?

An A record maps a domain name to an IPv4 address. When you visit a website, your browser looks up the A record to find the server's IP address.

What is an MX record?

MX (Mail Exchange) records specify the mail servers responsible for receiving email for a domain. The priority number determines which server to try first.

What is TTL in DNS?

TTL (Time To Live) indicates how long a DNS record should be cached before checking for updates. Lower TTL means faster propagation of changes but more DNS queries.
