Basic information about DNS propagation

A Domain Name System (DNS) is a database system that translates domain names into IP addresses. This allows computers to find websites using a name that is easy to remember instead of a series of complex numbers. DNS acts as telephone directories for the Internet.

DNS propagation is the process by which updates to DNS records (IP addresses associated with a domain name) are propagated across the Internet. It can take up to 48 hours for new information to be available on all DNS servers worldwide.

Concretely, when you create a new domain name (or when you move it), you have to tell computers all over the world the new address of that domain name, which can take a little time (but in practice usually takes no more than a few hours).

The propagation is fully automatic. If you want to monitor the process, you can use a DNS checker, such as DNS checker https://dnschecker.org/
Enter your domain name and choose the NS option (for DNS).



Once the spread is complete, remember to clear your DNS cache if your site still doesn’t respond in order to update these changes on your computer or smartphone.
