6.5.8 does not mention it. It depends, instead, on the end-user assignment policy. This is done to ensure that
ARIN and LIRs are assigning blocks to end users from identical policy, including future changes to that
policy. It allows for consistency of policy maintained in a single place.

2010-8 provides for nibble alignment in end-user policy. Current end-user policy does not provide for
nibble alignment. I support 2010-8 and hope that it will be sent to last call shortly.

I'd like to avoid putting end-user policy snippets in the ISP Allocation policy if possible because I think
it confuses matters. However, if you still think this is a concern, let me know and I will attempt to address

No worries... The ### notation made it pretty easy to search. ;-)
