What is a DNS?

DNS stands for domain name servers, it controls domain name of website and email settings. These servers maintain a directory of the domain name and translate them to IP Addresses. It is like phonebook of the internet. It is easy to remember a name rather than numbers. DNS provides the same service, it is a phonebook for the internet.

For Example:
When you type PrePostSEO, Request will go to DNS and it will indicate to an IP Address that is associated with it. Then your browser will connect to the server and retrieve webpage.

What is DNS Propagation?

When you change or update Name Server of any domain, it may take up to 48 to 72 Hours for the change to take effect. This is called DNS Propagation. In the other hand DNS propagation is a term that used to describe the time that can be taken to make any changes in a domain name.

Every time when you write domain name in the address bar and hit enter, if you are visiting that website the first time. A request will generate to your local Internet service provider. The browser will not send a request directly to hosting server. It has to pass through several ISP nodes, your computer first checks local DNS cache. Then send a request to nearly ISP provider that provider sent to next one and so on. After passing all these paths request received to hosting server.

In this process cache of DNS will be stored in your device operating system cache. Purpose of saving cache is just improving the performance and making it fast. Next time when you will visit DNS that is stored local cache will be executed; this cache has an expiry time set. Therefor updating in Name Servers can take up to 72 hours.

In Simple words DNS propagation is just the time, it takes for all the DNS servers around the world to catch up with the new DNS updates.
