DNS Multi-Resolver
Simultaneously query DNS entries from 6 public resolvers and check for consistency
Multi-Resolver Consistency Check
The DNS Multi-Resolver tool allows you to verify how different global DNS providers interpret your domain's records. By querying six major public resolvers simultaneously, the tool identifies whether your DNS changes have propagated correctly or if there are inconsistencies between providers. This is essential for ensuring that users across different regions and networks see the correct IP addresses or records immediately after a configuration change, providing you with a clear overview of global propagation status.
Reliable DNS Propagation Tracking
Use this tool whenever you update your nameservers, A records, or MX records to ensure consistent delivery. It is an invaluable asset for web administrators and developers who need to confirm that their updates are live across multiple networks. Instead of checking one provider at a time, you can instantly see if all resolvers agree on the data, helping you pinpoint exactly where propagation issues might be occurring during your deployment process.
Data Handling and Security
This tool queries multiple DNS resolvers worldwide through our server because a browser cannot do this directly due to CORS. The domain you enter is sent to our server for this purpose, but it is not stored. This architecture ensures that you receive accurate results from various global providers while maintaining a secure environment where your input data remains transient and is never saved in any database.
Frequently asked questions
What is DNS propagation?
DNS propagation is the process of updating your domain's records across all servers on the internet. When you change settings, it takes time for every provider to update their cache. This tool helps you track this progress by checking multiple resolvers at once to see if they provide consistent information.
Why do different resolvers show different results?
Different resolvers can show inconsistent results due to varying cache expiration times or geographic locations. If a resolver has not updated its records yet, it will provide an old IP address. Our tool highlights these inconsistencies so you can identify which providers are still showing outdated information after your update.
Is my domain data safe?
Yes, your privacy is respected. Because browsers cannot query multiple DNS resolvers directly due to CORS restrictions, the domain you enter is sent to our server for processing. However, we do not store any of the information submitted during the check, ensuring that your queries remain private and transient.
How often can I use the tool?
To ensure fair access for all users, guests are limited to one request per minute. This allows you to perform thorough checks on your DNS records while providing a reliable way to verify consistency across multiple global providers during your deployment process without overwhelming the system.
