Randy is correct - while "organization ids" do map to organizations,
it is often a many-to-one relationship and hence not necessarily useful
as an indicator of number of organizations (in the typical use of the
term) actually involved.  It is a valid upper bound, but the true value
may be less due to multiple network management entities (Foo-wireline, 
Foo-wireless, etc.), multiple contracts with ARIN, or multiple entries 
for hierarchical organizations (e.g. large governments with multiple 
agencies/departments)
