Some conclusions;

Many of the names and organizations with the largest number of entries are
generic entries. For example, there are 135 name entries with some version
of "Admin" or "Administrator" and 52 organization entries with some version
of "Private."

Nevertheless, at least a handful of what seem to be real organizations in
the registry purport to use more than 10 ULA prefixes. The limitations of
the new known-local ULA list in draft-ietf-6man-rfc6724-update could be
problematic for these organizations.

Also, given the number of names and organizations with multiple entries,
there seems to be some evidence for the need for ULA-C prefixes shorter
than /48, especially if an organization's justification for shorter
prefixes can be evaluated.
