The United Kingdom is one of the world’s top internet users, with over 80 percent of its population online. The country has two domain names – ‘uk’ and ‘www.’ While both are valid web addresses, they have different purposes; uk is used for national websites relating to businesses and organisations in the UK, while www is a global address used for international sites. Both domains can be registered through Nominet, an organisation that oversees the management of .UK domain names. With more than 10 million active .uk domains registered as of 2019, it remains one of the most popular country-code top level domains in Europe.
