Propagation for your DNS server

If you want to register a new domain name or make changes to an existing domain name (which means changes to the DNS servers), then an update to the information stored in name servers across the Internet is required.

Propagation is the name of this updating process, which occurs when domain name servers (DNS) update their records (DNS tables) on the Internet world-wide. This is to reflect any updates to domain names and IP addresses.

You will receive a new IP address for a domain if you move that domain from one host to another. The DNS of your new host will then be updated with the location of that IP address.

This new location for the domain will mean that all other DNS servers in the world need to be updated with this information. Different hosts update the DNS servers at varying intervals, and can be anywhere between 1 hour and 1 week.

"Propagation" is the time taken between the initial change being made and all the world's DNS servers being updated with the new information.

It comes from the original meaning of the word propagation - "The process of spreading to a larger area or greater number".

How long does propagation usually take?

Propagation in general takes about 24-48 hours. Although sometimes it can take up to a week.

When propagation is taking place, the traffic is decreasing at the old location at the same rate it is increasing at the new location.

It is up to the ISP how often it updates its DNS, and we update ours every 3 hours.

Unless every ISP updated more often then nothing can be done to speed up the propagation process.
