Nameservers, special computers accessible on the Internet, that tell where a website is located. Nameservers are responsible for resolving, a special process in which a domain name matching your website is taken and a physical address is obtained.
The resolving process begins when a visitor goes to your website. The visitor enters your domain name in the Internet browser.The browser then searches the nameservers about the location of the server to find out just where your website is located. Then, it connects to the server and opens your web page. The whole process is similar to looking through a phone book. For example, when you pick up the phone book to look for the name John Doe, it is like the beginning of the resolving process, just like typing a name into the Internet browser. When you find the phone number, you have resolved the process, just like a nameserver helps find a website address!
While the resolving process is not something you as the website developer must complete or even need to understand, you do need to know some of the information. You will need to provide the names of the nameservers when you buy or set up your domain name. Your web host will assign your nameservers when you sign up for hosting.
When switching hosts, you'll also need to change your name servers for your domain to the new hosts nameservers.
Keep in mind that propagation time for changed or new nameservers can take up to 48 hours
propagation is the time period it takes to get the adjusted nameservers published across the entire world wide web.
For example you may be able to view your site on the new hosts server 1 hour after adjusting your name servers while folks in a different area of the country may not for several hours as the adjusted name servers propagate.
Our servers normally propagate name servers in less the 24 hours.
