there is no "wildcard capability in zone file specifications that
matches _all_ sub-domains" [emphasis mine].  wildcards do not match
subdomains of themselves.

if RPZ is "just DNS", then i see no way to create an RPZ rule that can
match the following name, short of setting the RPZ origin name to ".":

*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.bad.com.
