What is DNS Propagation?

DNS (Domain Name System) propagation refers to the process by which the changes made to a domain’s DNS records are propagated or spread across the internet. When you update the DNS records for your domain, such as changing the IP address associated with a particular domain name, it can take some time for these changes to be reflected and propagated across all the DNS servers and caches that exist on the internet.

During this propagation period, some users may still see the old DNS records while others will see the updated records, depending on which DNS server they are using and whether it has cached the old or new records. The propagation time can vary from a few minutes to up to 48 hours, although it typically takes around 24 hours for changes to be fully propagated across the internet.

It’s important to note that DNS propagation is not a precise science, and there are many factors that can influence how long it takes for changes to be fully propagated. Some of these factors include the TTL (Time To Live) value set for the DNS records, the number of DNS servers and caches that need to be updated, and the frequency with which those servers refresh their caches.

To check the progress, you may utilize online tools like DNS Checker. All you need to do is enter your domain name, select the DNS record type, and click on the Search button.

DNS Propagation

Here is a guide about the different types of results you may get:

  • All cross marks ? – Usually you get it if you have recently added new DNS record. Typically it takes 24-48 hours for the propagation.
  • A combination of cross marks ? and check marks ? – The propagation is in process and should be completed within 24-48 hours time from its update.
  • All check marks ? – Usually it indicates that DNS record is propagated.
