NTA currently displays the country of origin for IP traffic based on the country registration with ICANN. It displays all private addresses as "Private Addresses". We own 6 class B's and more class C addresses than I can count, plus utilize a number of Private Address ranges. Problem is, all of them that are registered are US registrations, so an address that we use in Russia or Norway shows up as a US address.
Allow administrators to set the country of origin for their own IP address spaces. IP address groups can be custom defined, why not the country of origin. This would be a big helper for companies that use mostly private addressing as well as those like mine.
