I too cannot support this policy as written, but also believe it is 
necessary for us to discuss this issue in Philly.

I would characterize the policy intent I would want to see as "new 
resources allocated from ARIN should be mostly used within the ARIN 
region", but I don't interpret that as meaning that 50% should be used 
within the ARIN region.  I think that means the usage within the ARIN 
region should be larger than any other individual region.

Today with globalization, I could see a someone claiming ARIN as their 
home region and still have more total resources in use outside the 
region.  But for ARIN to be their home region then the ARIN region 
should be the largest single region where their resources are used.  I 
think this would be especially relevant for multinational corporations 
getting direct assignments from ARIN, but probably ISP too.

So I would suggest wording something like; "IPv4 addresses obtained from 
ARIN may be used within another RIR's region.  However, use within any 
other individual RIR's region must not exceed the use within the ARIN 

So as an example, I could see a multinational company based in the US or 
Canada having resources from ARIN and use its resources among the 
regions as follows; 30% ARIN, 30% APNIC, 25% RIPE, 10% LACNIC, 5% 
AfriNIC  Most of the resources are not used within the ARIN region, but 
none of the use in the other regions exceeds the use in the ARIN region.

To me this seems like a reasonable requirement for use of resources from 
the ARIN region, without being overly restrictive, this could possibly 
even work for IPv6 addresses too.  Furthermore, it maintains a logical 
reason to have regions in the first place.  Finally, I don't think this 
should create a problem for any organization that really thinks of 
itself as primarily an organization from the ARIN region.

If that seems to wishy-washy, then I could also go with something like 
"use must be no less than X% in the ARIN region, and use within any 
other individual RIR's region must not exceed the use within the ARIN 
region."  Where X equals something like 25, 30, or 35%. But, requiring 
50% usage within the ARIN region doesn't seem to take into account the 
realities of globalization today.
