Everything you ever wanted to know about a ccTLD
Every internet address, or domain, has a domain ending, also known as a top-level domain. Country code top-level domains (ccTLDs) are used to indicate the site’s relation to a specific country or region (i.e. .uk for the United Kingdom or .eu for the European Union) and are therefore referred to as country code TLDs.
Alternative uses for ccTLDs
Generic top-level domains provide the counterpart to ccTLDs. These don’t have a regional domain extension, but rather refer to a specific theme (such as .com for commercial/business enterprise or .org for an organization) and can include more than two letters. However, some ccTLDsare repurposed and, like gTLDs, can be used to indicate particular types of websites or the genre of content or products. Wordplay with certain country codes is also quite common.
