The RFCs would also suggest that the final component of a domain could be
longer than 4 characters. In fact, accommodating that has been a clear
operational requirement for some time, as it's long been threatened that
such domains would exist in the primary root, and for people who use the
various splinternet alternate roots, it's been reality for years.
