A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet.
Your website also has an IP address made up of a string of numbers (similar to xxx.xxx.xxx.xxx). Instead of requring your visitors to remember that confusing string of numbers to visit you, your visitors can instead just type in your domain name. This is thanks to what is know as the domain name system (DNS).
DNS is simply a group of computers that translates your domain name into your numerical IP address. After all, computers communicate via numbers and not words.
How does DNS work? If you want to visit WORLDBUS website, all you need to do is remember the domain name “worldbus.ge”. You do not need to know the related IP address made up of the string of numbers. When you type in worldbus.ge into your browser, your request is sent to DNS and DNS looks up the IP address for worldbus.ge and directs you to our website.
