Overview
The DNS Query Tool allows you to perform real-time lookups for domain records, providing instant visibility into how your domain is configured across the internet. Whether you are troubleshooting connectivity or verifying DNS propagation, this utility retrieves accurate A, AAAA, MX, TXT, NS, and CNAME records with ease.
When to Use
- •Verifying that your domain's IP address is correctly mapped after a server migration.
- •Checking if email delivery issues are caused by misconfigured MX or TXT records.
- •Confirming that DNS changes have propagated globally across different nameservers.
How It Works
- •Enter the domain name you wish to investigate in the input field.
- •Select the specific record type (e.g., A, MX, TXT) or choose to view all available records.
- •Optionally specify a custom nameserver to query if you need to bypass default system resolvers.
- •Click the query button to receive a detailed breakdown of the requested DNS records.
Use Cases
Validating SPF and DKIM configurations by inspecting TXT records.
Debugging website downtime by checking if the A record points to the correct server IP.
Managing mail server transitions by verifying updated MX record priority and destination.
Examples
1. Verifying Email Configuration
System Administrator- Background
- The company recently switched email providers and users are reporting missing incoming mail.
- Problem
- Need to confirm that the MX records are correctly pointing to the new mail server.
- How to Use
- Enter the domain name, select 'MX' from the record type dropdown, and run the query.
- Outcome
- The tool displays the current MX records, allowing the admin to identify that the old provider's records were still active.
2. Troubleshooting Website Connectivity
Web Developer- Background
- A client's website is unreachable after a recent DNS update.
- Problem
- Determine if the domain is resolving to the correct server IP address.
- How to Use
- Enter the domain name and select 'A' record type to see the current IPv4 mapping.
- Outcome
- The output shows the domain is still resolving to the old server's IP, confirming a propagation delay or configuration error.

FAQ
What is an A record?
An A record maps a domain name to its corresponding IPv4 address.
Can I check records from a specific nameserver?
Yes, you can input a custom nameserver address in the optional field to perform a targeted lookup.
What does a CNAME record do?
A CNAME record maps an alias domain name to the true or canonical domain name.
Why are my DNS changes not showing up?
DNS changes can take time to propagate globally due to TTL (Time to Live) settings on cached records.
What is the difference between A and AAAA records?
A records are for IPv4 addresses, while AAAA records are for IPv6 addresses.
