Serves me right to try to respond off the top of my head without
checking the reference. :)
You're right, 952 talks about the DOD Host Table, and predates period-
separated labels forming a FQDN becoming ubiquitous. Most of what it
dealt with are single-label names in that host table.
The OP should be looking to RFC1035 section 2.3.1 for the
specification for modern host names.
