 What do the domain extensions mean? (co.uk or .com etc)
Solution

Domain extensions, or suffixes, are categories of Internet domain names, and serve to describe the type of company, organisation, country or other category.

The technical term used for domain extensions is top-level-domain (or TLD). There are many categories from which to choose, and some extensions are more popular than others.

Be aware that for the majority of domain extensions, some exceptions apply, the category the domain claims to represent is not enforced. A domain name with the extension .co.uk may be representing a uk based business, but you cannot rely on this as anybody is allowed to register a .co.uk domain name.

Please find below a list of the most common domain name extensions used, a description of the category they are meant to represent, and whether any restrictions apply.

Restriction on registry: None.

Extension: .co.uk
