DNS propagation explained

Posted on by Hans

DNS propagation is a period of time in which it takes updates to DNS records to be in full effect over all of the servers on the web. The reason changes aren’t immediate is because nameservers save domain record data in their cache memory for a particular amount of time before they refresh. So while your domain won’t experience any downtime from well-planned record changes, some users will still be served a cached version of your website until all servers have propagated.

Usually, DNS propagates within a few hours, but it can take as long as 72. The time for propagation is based on different factors, such as your internet service provider (ISP), your domain’s registry, and the TTL values of your DNS records.

What is the Domain Name System?

Posted on by Hans

The Domain Name System, also known as DNS for short, is the Internet’s system for linking alphabetic names to numeric Internet Protocol (IP) addresses. It is like a phone book that maps a person’s name to a phone number. For illustration, when a Web address (URL) is typed into a browser, a DNS query is created to get an IP address of a Web server correlated with that name.

For example, when using the www.example.com URL, example.com is the domain name, and www is the hostname. DNS resolution maps www.example.com into an IP address (like 123.4.56.78). When a user wants to view a webpage, a conversion has to happen between what a user types into their web browser (www.example.com) into an IP address needed to locate the www.example.com website.
