11.11.2019 yahe administration update
35 years ago the IETF defined special IPv4 addresses in RFC 1597 to be used solely in private intranets and with that created the separation between internal networks and the internet. 5 years later they proceeded to define special-use top-level domains like .example
, .invalid
and .test
in RFC 2606. However, the IETF did not reserve a top-level domain to be used within the private intranets that they had introduced before. This lead to confusion with administrators that still persists to the current day.
