The World Wide Web is based on unique numbers known as IP addresses and every device or site that is a part of the Web has such an address. It is pretty hard to remember to go to 123.123.123.123 to see a website though, so a significantly quicker system was created in the eighties - domain names. Every single domain name is made of a primary part and an extension, to give an example domain.com or domain.co.uk. A great number of extensions exist worldwide - part of them are assigned to countries, such as .co.uk in the abovementioned example, which is given to the United Kingdom, while others are generic, such as .com or .net. Many extensions are available for registration by any entity and some others have certain requirements - business registration, local presence, etcetera. You will be able to get a brand new domain name through a registrar organization like ours and if the extension supports domain transfers, you're able to move an existing domain name between registrars as well.
