What is a Domain Name?

Posted by: Maxine Brimmer (3 years, 1 month ago)

Sometimes known as a DNS, a domain name system is the technology used to manage the names of websites and internet domains. The domain name system exists largely to provide each website with a memorable address which can be easily remembered by users or clients, rather than using complicated IP addresses to identify websites.

It can be easy to confuse a domain name with a URL, but they are not exactly the same thing. Instead, a domain name forms part of a URL, for example in the address: www.processlibrary.com/en/blog/?page=2. In this example the bold “processlibrary.com” is the domain name, which is a part of the entire address, known as a URL.

There are a few important rules when domain names are created; domains are not case sensitive, and they may not contain spaces, though they may contain numbers or dashes. Domain names are divided into top-level domain name, which contains more generic information, and second-level domain names, which are more specific. In the example of www.processlibrary.com, “.com” is the  more general top-level domain name, and “processlibrary” is the far more specific second-level domain name.
