A domain name is the website name that online users type into a browser to access a website on the internet. SiteCare’s domain name, for example, is sitecare.com.
Web browsers need these domain names to be translated into Internet Protocol (IP) addresses so that machines can connect and interact with each other across the internet. To be understood by other machines, IP addresses are numerical (made up of a string of numbers) and difficult to memorize, which is why domain names were created instead.
The internet’s Domain Name System (DNS) is a directory that holds records of all existing website domain names and their matching IP addresses to find resources (like web pages) online.
