[rpd] Comments on AFPUB-2018-V6-001-DRAFT01

[Owen DeLong]

I oppose this policy.

It is absurd to hand out /31, /30, /29, etc.

If you need more than a /32, we should simply hand out a /28.

If you need more than a /28, we should hand out a /24, etc.

There’s no reason in IPv6 for non-aligned (nibble boundary) blocks to be handed out. It’s a complete waste of human resources and it makes things more error prone.

Rather, if we are going to open this particular can of worms, I’d like to see us model things more along the lines of the current ARIN policy:

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.

It may not work if an ISP has now 50.000 customers and they have a huge investment plan to make 200.000 customers in very few months, but of course, they can then go back for more to AfriNIC.
