The World Wide Web is based on unique numbers known as IP addresses and every unit or website that is a part of the Web contains this kind of an address. It would be pretty hard to remember to go to 220.127.116.11 to open a website though, so a much quicker structure was made in the 80s - domain names. Every single domain name consists of a main part as well as an extension, for example domain.com or domain.co.uk. A plethora of extensions exist globally - part of them are given to countries, for example .co.uk in the abovementioned example, which is given to the United Kingdom, while others are generic, for instance .com or .net. Many extensions are available for registration by every entity and some others have certain requirements - company registration, local presence, etcetera. You will be able to get a brand new domain through a registrar organization like ours and when the extension allows domain name transfers, you can relocate an existing domain between registrars too.
