'.example' is a
reserved top-level domain not intended for real use in the global
DNS. It was defined in June 1999 by RFC 2606, along with
.invalid,
.localhost, and
.test.
The stated purpose for the creation of ".example" was to provide TLDs for examples in documentation and other technical writing, such that conflict with global DNS can be avoided. However, it has been criticised for not being "real enough", as it is longer than real TLDs: all existing TLDs except the relatively esoteric
.museum and
.travel have at most four characters.
