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. 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!
