New submission from Allayna Wilson <allaynawilson at gmail.com>:

import IPv4Address as n4

In [10]: n4('100.64.0.0/24').is_private                                                                                     
Out[10]: False

In [11]: n4('100.64.0.0/10').is_private                                                                                     
Out[11]: False
