A domain name is the actual name of a website, and every single website has a domain name. To obtain one, you need to purchase it through a domain registrar. Every domain name is actually pointing to an IP (Internet Protocol) address, which is a series of numbers. Because most people can’t remember 10 digits in perfect order, domain names serve as easily-remembered alias for visitors. Probably the best known domain name is google.com, and Google’s IP address is 184.108.40.206… which is easier for you to remember?
