Reserved DNS names
The reasons for reservation of these top-level domain names is to reduce the likelihood of conflict and confusion. This allows the use of these names for either documentation purposes or in local testing scenarios.
The top-level domain example is explicitly intended to be used in documentation or other technical writing, when domain names are presented as examples in usage or presentation of concepts of the Domain Name System or the Internet.
