[arin-ppml] AFRINIC And The Stability Of The Internet Number Registry System

[Michel Py]

Hi list and ARIN,

I have a dumb question : under what conditions is it OK to use an ARIN IP address in another RIR region ?

I have a specific situation in mind : a global organization (with physical infrastructure in all 5 RIRs) is using ARIN addresses in a country in the RIPE region (and most likely elsewhere).
I do not want to point fingers, as I suspect that this is a quite common situation. But it is related to the subject at hand.

Thanks for your enlightenment.

Michel.
