Just as a historical note, while RFC 952 is not officially obsolete, its purpose
was to specify the format of the HOSTS.TXT file, which is, in fact, obsolete.
Later RFC's, of course, incorporate by reference the restrictions of RFC 952,
disembodied from the HOSTS.TXT context in which they were originally conceived.
Query: was HOSTS.TXT file inclusion ever enforced as a prerequisite for Internet
connectivity?
