How to use the DNS lookup tool

  1. Enter the domain

    Type the domain name (e.g., example.com) you want to look up.

  2. Select record type

    Choose the DNS record type you want to query (A, MX, TXT, etc.) or select 'All' for a complete overview.

  3. Run the lookup

    Click 'Lookup' to query DNS servers and return all matching records.

  4. Review records

    See the returned DNS records with their values and TTL settings.

  5. Diagnose issues

What is a DNS lookup tool?

The DNS Lookup tool performs real-time DNS queries for any domain, returning all major record types: A (IPv4 address), AAAA (IPv6 address), CNAME (canonical name), MX (mail exchange), TXT (text records including SPF and DMARC), NS (name servers), and more.

DNS (Domain Name System) is the internet's address book — it translates human-readable domain names into IP addresses. Understanding your DNS configuration is essential for troubleshooting website accessibility issues, verifying email server setup, confirming domain ownership, and diagnosing propagation delays after DNS changes.

Why use a DNS lookup tool?

DNS misconfigurations can make websites unreachable, cause email delivery failures, and create domain verification failures. Before diagnosing a site outage, checking DNS records is often the first step. This tool lets you perform instant DNS lookups without using command-line tools.

DNS lookup tool: frequently asked questions

Something else? Ask the team

What is a DNS A record?

A DNS A record maps a domain name to an IPv4 address (e.g., 93.184.216.34). It tells browsers which server IP to connect to when visiting your domain.

What is a CNAME record?

A CNAME (Canonical Name) record maps a domain alias to another domain name. For example, www.example.com might CNAME to example.com, meaning both point to the same server.

What are MX records?

MX (Mail Exchange) records specify which mail servers handle email for your domain. Without correct MX records, email sent to your domain won't be delivered.

What is DNS propagation?

DNS propagation is the time it takes for DNS changes to spread across the global network of DNS servers. Changes can take anywhere from a few minutes to 48 hours to propagate globally.

What are TXT records used for?

TXT records store arbitrary text data. They're commonly used for domain verification (Google Search Console, domain ownership), SPF records (email authentication), and DMARC policies.
