:Hi all,
:
:As you probably know, ARIN amended some time ago their IPv6 policy proposal in order to make sure that the allocations to LIRs are aligned to the nibble boundary.

:In the context of another discussion in AfriNIC, Owen DeLong, suggested that we could do something similar.

:I'm considering submitting a policy proposal in each RIR (RIPE, AfriNIC, LACNIC, APNIC), for that, but I will like to get some inputs before, and "sense" the feeling about that of the participants.
:
:Note that in the case of RIPE, we have a big difference with the other RIRs, because all them start with /32, while we updated our policy several years ago (because 6rd deployment), to allocated /29. This means that if we go for this policy, it will be justified to "upgrade" all the /29 allocations to a /28.

Using this justification, would that also grow all IPv6 PI /48s to a /44,
or only those that are not already at a nibble boundary?


:This is the example that Owen sent to the AfriNIC list:
:
:1.	Figure out the number of end sites you expect to serve in your largest aggregation point
:	in 3-5 years.
:2.	Round that to a nibble boundary (with a 25% minimum free space) (1-12 end sites = 4 bits,
:	13-192 end sites = 8 bits. 193-3,072 end sites = 12 bits, 3,073-49,152 end sites = 16 bits,
:	49,153-786,432 = 20 bits, etc.)… Call this E.
:3.	Figure out the number of aggregation points you expect to have in 3-5 years. Round that up
:	to a nibble boundary with a 25% minimum free space (same as in step 2). Call this A.
:4.	48-(A+E) = prefix size.
:
:	Example: An ISP has 42,000 customers in it’s largest end site. It has 128 end sites.
:		E = 16, A = 8, 48-(16+8) = 48-(24) = 24, this ISP should get a /24.
:
:So, would you agree in doing something on this line?
:
:Thanks in advance for any inputs!

:Regards,
