A domain name is really just your address on the Internet. It’s where people can find you, and it serves as your online identity.
Businesses typically register domain names with their company name and sometimes also register their product names. Individuals often register family names or names that have a personal interest to them. Domain names have two parts: the label and the extension, or top-level domain, separated by a ‘dot.’ In mitsol.net, ‘mitsol’ is the label and ‘net’ is the top-level domain.
There are over 20 domain name extensions to choose from. Popular domain name extensions such as .COM, CO.ZA and .NET are typically used by for-profit companies, while .ORG is often used to denote a non-profit organization. Other generic extensions such as .INFO and .BIZ have more recently become available as well.
You can also register domain names that are specific to a certain country. For example, the extensions .US, .UK, and .DE correspond to the United States, United Kingdom, and Germany, respectively.
