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 enroll in their hosting service. Other than that, let the computer and name server handle the rest. All you have to do is get your web page designed and on the World Wide Web!
