What is DNS Propagation?

DNS propagation is the time it takes for DNS changes (like updating an IP address for your domain) to be updated across all DNS servers worldwide. This process can take anywhere from a few minutes to 48 hours, or sometimes longer, depending on various factors like TTL settings and ISP caching.

Why Does DNS Propagation Take Time?

DNS servers around the world cache DNS records to speed up website loading and reduce traffic. When you update a DNS record, these servers need to refresh their cache to get the new information. The Time To Live (TTL) value set for your DNS records dictates how long servers should cache the information before checking for updates.

Can I Speed Up DNS Propagation?

While you can't directly control the internet-wide propagation speed, you can prepare for faster updates by lowering the TTL values for your DNS records *before* making changes. A lower TTL (e.g., 300 seconds / 5 minutes) tells servers to check for updates more frequently. However, setting TTL too low can increase load on DNS servers.

What should I do after changing my name servers (NS)?

After updating your name servers at your domain registrar, propagation can take 24-48 hours. During this time, traffic will be directed by both your old and new name servers. Use this tool to check your NS records. Once servers worldwide consistently show your new name servers, you can safely decommission the old ones.

Why do I see the old IP address but other people see the new one?

This is the classic DNS propagation issue. Your local computer or ISP has a cached (saved) copy of the old DNS record and is waiting for its TTL to expire. Other users in different regions are using different DNS servers that may have already updated to the new record. Our tool helps you see this global status from a neutral perspective.

What if my DNS changes are not propagating?

If changes aren't propagating as expected. Double-check that you saved the DNS changes correctly at your domain registrar or DNS hosting provider. Verify the nameserver settings for your domain are correct. Ensure the TTL values weren't excessively high before the change. Wait a bit longer, as some locations can be slower to update. If problems persist after 48 hours, contact your DNS provider for support.

How can I check if DNS propagation is complete?

You can use online DNS checker tools. These tools allow you to check DNS records from multiple geographic locations, giving you a global view of the propagation status.

Can DNS propagation affect my website's availability?

Yes, during the propagation period, some visitors might be directed to your old server while others are directed to the new one. This can lead to inconsistent experiences or temporary unavailability for some users.

Global DNS Propagation Checker

Instantly check the live propagation status of your DNS records. Ensure your domain changes are live worldwide to troubleshoot issues and minimize downtime.

Check DNS Records Propagation

Enter a domain and select record type to see its propagation status across global DNS servers.

Domain Name

Record Type

DNS propagation can take time. Results show current status from various global servers. If the record does not exist then it will show as "Not Propagated".

Understanding DNS Propagation

Our Online DNS Propagation Checker is a powerful tool designed to help you track the spread of your domain's DNS record changes across the internet. Whether you've updated your website's IP address, changed mail servers, or modified other DNS settings, this tool provides a real-time view of how these changes are being reflected by various DNS servers globally. Avoid costly website downtime and troubleshoot issues. Understanding DNS propagation is crucial for ensuring your online services remain accessible and function correctly after any DNS modifications.

Troubleshoot DNS Propagation Delays

When you ask "Why are my DNS changes not reflecting yet?", this tool gives you answers. Here are the common scenarios you can diagnose in real-time.

Verifying a Website Migration

After changing A or AAAA records, use this tool to confirm your new IP is live globally before decommissioning an old server to prevent downtime.

Solving Email Delivery Failures

If emails are bouncing after a provider change, check the propagation of your new MX and TXT (SPF/DMARC) records to ensure mail is being routed correctly.

Check Name Server Updates

When switching DNS providers, monitor your NS record propagation. Use this tool to see when servers worldwide recognize your new authoritative name servers.

How DNS Propagation Works

When you update your domain's DNS records with your DNS provider, these changes aren't instantaneous worldwide. The process involves several steps:

Authoritative Server Update: Your DNS provider updates the records on their authoritative DNS servers.
TTL (Time To Live): Each DNS record has a TTL value, which tells other DNS servers how long to cache the record's information. Common TTLs range from a few minutes to 24-48 hours.
Recursive Server Caching: Internet Service Providers (ISPs) and public DNS resolvers (like Google DNS or Cloudflare) run recursive DNS servers. When a user tries to access your domain, their recursive server queries the authoritative servers. It then caches the result for the duration of the TTL.
Cache Expiration and Refresh: Once the TTL expires, recursive servers will fetch the updated record from the authoritative servers the next time they receive a query for your domain.

This staggered update process across thousands of servers worldwide is known as DNS propagation. Our tool queries multiple geographically distributed DNS servers to show you which ones have the latest information and which are still using cached, older records.
