How domain names work.

Updated on May 10, 2012

Just think of a domain name as a unique name that identifies the web files that you have stored on your web server. For instance, to access this page, you used the domain name the world wide web is an interconnection of many computers from all over the globe. Each of these computers have a unique IP address (IP is an acronym that stands for Internet Protocol). The IP is what identifies and distinguishes one computer from the other. The IP address consists of four numbers. For instance, an example of an IP is

For you to be able to connect to any of the computers on the internet, you would need to know the IP address of that computer. However, the numbers are very hard to remember for most people. Imagine if instead of typing in the address bar, you had to type in (the IP address)…I don’t need to be psychic to know that you would hate the internet! Luckily however, there is a way around this- domain names

The domain names are the human friendly versions of the machine friendly IP addresses. When you enter a domain name in the address bar, it is translated into the equivalent IP address before the files are loaded for you to view what you are actually looking for. The domain name system (DNS) is in charge of this process. It is the DNS that translates your domain name into the IP and also translates the IP into a human friendly version for you to view it in the URL bar of your browser. You can read more on how the DNS server works by following this link.

So where does one get a domain name? You register it from a registrar. These are companies that deal with selling and reselling of domain name on the internet. Anytime you register a domain, your contact information like your email address, your name as well as your telephone numbers are required. These details are usually associated with your domain. This means that If anyone checks the whois records via a domain tool that allows for such checking, he will get all your contact details, unless in some situations where only your email address will be displayed.
