Domain Name Servers: The BasicsTechnically, domain names aren't necessary to access a website. This is because with or without them, all websites can be accessed by their corresponding IP address. What is an IP address? It is a 32-bit numerical identifier that indicates what machine a website is on. The only problem is that for a human these numbers ... use instead. Yet, if they do get a domain name server, they would have the ability to sell web hosting as well as domain names to their customers.
