No matter which statistics you look up, more than half of all Internet addresses have the extension .com. Also high up in the rankings are the other two generic top-level domains .net and .org. Like .com, these have been around since 1985. The other domain extensions in the top 10 are primarily country code TLDs (ccTLDs), which are country-specific.
Among the country code top-level domains, highly populated countries such as Russia and India are ranked up top, as are other countries with a high level of digitalisation, such as the United Kingdom and Germany. The right to use a .uk domain extension has a slightly complex history. Most people will know that .co.uk is a typical domain extension for UK websites, but in June 2014, a shorter version was launched: .uk. The use of this domain ending was reserved for websites that already had .co.uk endings, or endings such as .gov.uk. This was to prevent cybersquatting and URL hijacking, but there was a time limit to these reservations and businesses had to actively claim the .uk domain extension. This reservation expired in 2019. A UK address is required to register a .uk domain extension. .
