The World Wide Web is based on unique numbers identified as IP addresses and every unit or web site that is part of the Web has this kind of an address. It would be very difficult to remember to visit 188.8.131.52 to see a website though, so a significantly quicker structure was launched in the 80s - domain names. Every single domain name is made of a primary part as well as an extension, to give an example domain.com or domain.co.uk. Plenty of extensions exist worldwide - part of them are assigned to countries, like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while others are generic, for instance .com or .net. Some extensions are available for registration by every entity and some others have precise requirements - company registration, local presence, etc. You're able to acquire a new domain via a registrar organization like ours and if the extension allows transfers, you'll be able to shift an existing domain name between registrars too.
