========

Two Modest Proposals

  o  A proposed host address range allocation

  o  A proposed address assignment allocation method

========

Host Address Range Allocation

  o  Reserve the last 16 bits of the 128 bit address space
     for host addresses only

  o  Pros

     -  2^16 hosts per net (or 65,534 available addresses)

     -  No need for network classes, subnets, masks, etc.

     -  Simplicity - it will ease human and machine recognition
        of address usage

  o  Cons

     -  Only 2^112 network addresses are still available (i.e.,
        only 5.2e21 trillion networks are still available)

     -  Inflexible

========

Address Assignment Allocation Method

  o  Charge for network address allocations using the following
     algorithm:

        $10.00US + $.10US * (X-1) = the total charge for X number
        of network addresses per application

  o  Use revenues to fund Internet activities
  
  o  Pros

     -  Vastly simplify the allocation process

     -  Everyone can afford one (or a hundred)

     -  educe waste and increase address usage efficiency

  o  Cons:  NONE
