DNS Lookup Tool

About the DNS Lookup Tool

Looks up DNS records (A, AAAA, MX, TXT, NS, CNAME) for a domain directly from your browser via Google's public DNS-over-HTTPS API.

How to use

Enter a domain and choose a record type, then click Look Up.

Worked example

Looking up example.com (A) returns its IPv4 address records.

How to use this calculator

1. Enter the domain name you want to check, such as example.com.
2. Choose the record type if the tool lets you narrow the lookup, or leave it set to retrieve common DNS records.
3. Run the lookup and wait for the DNS-over-HTTPS results to load.
4. Read the returned records and compare them with what you expected for the domain.

Step by step method

1. Type the domain into the lookup field exactly as it is used on the web.
2. Submit the request so the tool can query DNS servers over HTTPS.
3. Review the record output, such as address, mail, name server, or text records.
4. Use the results to verify site setup, email routing, or domain configuration.

Worked example

Suppose you want to check the DNS records for example.com before updating a website or email setting.

1. Enter example.com into the DNS Lookup Tool and run the search.
2. Wait for the tool to query the DNS-over-HTTPS endpoint and display the available records.
3. Review the results to see which values the domain currently publishes, such as its address and name server entries.

Tips and common mistakes

• Use the exact domain name, and do not include extra words, spaces, or a full URL.
• If a record is missing, try a different record type instead of assuming the domain has no DNS.
• Remember that DNS changes can take time to appear everywhere, so a recent update may not show immediately.
• Use the results as a diagnostic check, not as proof that a website or email service is fully working.
