IANA also reserves TLDs like '.test' and '.example' as well as some IDN equivalents.

There are also documentation and example IP prefixes! 192.0.2.0/24 and 2001:db8::/32.
And .local, right?
Actually, no. According to RFC 2606 - Reserved Top Level DNS Names, the following four domain names are reserved:

  .test
  .example
  .invalid
  .localhost
