A domain name is the address of your website. For example, imagine the internet as a map full of addresses, streets, and houses. The website is your house. In order to anyone to find a way to your house, you’ll need an address. This address is your domain name.
Every website has an IP address (eg: 71.287.131.106). It is difficult for people to remember the IP address every time they want to visit your website. Therefore, the domain name is like a simple, easy-to-remember name that anyone can enter it to visit your website.
