International domain names only consist of connections like .org, .com, .gov, .edu, .id and .net. They are still used for the same purpose as domain names, but they have a wider reach,
International domain names are great for businesses that want to reach a worldwide audience. There is no limit to your scope with an international domain name.  They are most commonly used for companies, organisations and departments that have outlets and are located within different countries. If you think your product or service could be targeted at a worldwide audience an international domain name is the way to go.
