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).

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, :Jordi : : : : : :********************************************** :IPv4 is over :Are you ready for the new Internet ? :http://www.consulintel.es :The IPv6 Company -- Broad-mindedness, n.: The result of flattening high-mindedness out.
