“Think about it. Every “box” ever invented was based pretty much on the same premise: how to get SOMETHING for NOTHING. In other words, to RIP OFF. Well, taking this concept to its logical conclusion, we end up with a “box” that simply CREATES MONEY. Yes, CASH wherever you need it. Not JUST for phone calls, but for pizza, cigs, laptops, v.fast modems, parking meter fares, YOU NAME IT. YOU DECIDE. The box… PROVIDES.

Of course, the electronics required to build this wonder have not been invented yet, but I will try to explain. First off, the box must of course be green. But not just ANY color of green. It must be MONEY GREEN. Maybe even a picture of George Washington on the back. As for buttons, there will be just ONE. A BIG, GOLD button in the center of the box… labeled “CASH.” And when pressed, the sound of cash registers will emanate from the unit - “Ka-CHING!”

I believe the main circuit should be a rectifier… to rectify the situation in YOUR FAVOR. Many capacitors (the green, electrolytic type) are to be arranged in a pattern on the PCB as such:

The current IPv6 Address Allocation and Assignment Policy (afpol-v6200407-000) suggests that most IPv6 subscribers should be assigned a /48 “in the general case”. The policy also requests AfriNIC to evaluate requests for additional allocations based on “units of /48 assignments” and that LIRs be allocated in general a /32.

Contrary to IPv4 where only utilization determines the level of consumption hence the threshold for subsequent allocations (80% host based utilization), in the IPv6 Policy efficient address space utilization threshold is used to determine eligibility to subsequent allocations. The HD-Ratio is a way of measuring the efficiency of address assignment [RFC 3194]:

Log (number of allocated objects)
HD = ——————————————
Log (maximum number of allocatable objects)

The efficiency utilization threshold (T) is expressed as a number of individual /48 prefixes allocated from an IPv6 prefix (P). It can be calculated as:

((48-P)*HD)
T = 2

The HD-Ratio presently defined for IPv6 is at 0.8.

This has the effect of making subsequent allocations to LIRs after only 10.9% utilization of their available space. If the allocation prefix is brought down to /20 the efficient utilization threshold will only be 2.1% using the HD ratio of 0.80. Based on this, the LIRs will have much more unused IP addresses than they really need for their efficient growth planning. (See ANNEX 1).

This policy proposal suggests to raise the HD ratio from 0.80 to 0.94. Doing this could allow to reduce by 3 bit the consumption of whole IPv6 address space over the next 50 years. An LIR will then qualify for a subsequent allocation only when its uses (for a /32) 51.41% of its allocation.

See: considerations.txt for more analysis on Issues Related to the Management of IPv6 Address Space.

** Similar adjustment of the HD-Ratio has been adopted in the other RIR regions **
