What is DNS propagation and how long does it take to complete?

"DNS propagation" is a term used to describe the time period until changes made to the domain or DNS zone information become visible regardless of where the queries are made.
This process is an automatic synchronization of DNS data globally and cannot be influenced.

You will need to wait for DNS propagation when:

- Make changes to the nameservers set on the domain.A complete propagation can take up to 48 hours. Generally, propagation occurs within a few hours.

- Make changes in the DNS zone. To increase the execution time of DNS queries, both local caches are created, on the device used for access as well as caches created on external servers and by the internet service provider. Each DNS record has a TTL (Time to Live) value, which refers to the time that DNS information is stored in cache. Once this time expires, on the next DNS query, the information will be refreshed. A complete propagation of DNS information can take up to 48 hours. Generally, propagation occurs within a few hours.

For all the cases above, it is recommended to clear the browser cache before checking if the propagation is complete.
