Whenever you open a website or type in the name of a website, such as www.yourdomain.com, it is translated to Internet Protocol (IP) addresses. That translation process is done by the Domain Name Servers.
We can say that the Domain Name Servers (DNS) are the Internet’s phone book. They preserve a listing of domain names and transform them to Internet Protocol addresses. This is required because, though domain names are easy for people to remember, but the computers or machines are made to access Web sites based on IP addresses.
The information from all the domain name servers from every corner of the Internet are gathered together and stored at the Central Registry. All the host companies and Internet Service Providers (ISP) get in touch with the Central Registry on a regular schedule to get updated DNS information.
When you open or type in a website address, say: www.yourdomain.com, the Internet Service Provider checks the DNS linked with the domain name, and translates it in a machine friendly IP address like (217.167.228.76 is the IP for yourdomain.com) and redirects your internet connection to the exact Website.
Once you register a new domain name or whenever you update the DNS servers on your domain name, it frequently takes around 12-36 hours for the domain name servers to be updated world-wide and able to access the information. These 36-hours period is referred to as propagation.
