[address-policy-wg] Policy Proposal Implemented: 2015-03, "Assessment Criteria for IPv6 Initial Allocation Size"

Dear Matt,

many thanks for the policy proposal implementation and for your e-mail.

I have one or two questions regarding the example in the information about the expanded evaluation criteria (link below).  I realise that you were just providing an example and all examples have their limitations.  I hope however that your answer might help me and possibly others to better understand the new policy.  The questions are:

a) if you have 8 cities each requiring a /48 then you need a /45 and not a /44 as in your example.   Is the extra bit already included in the /44?  This is not clear because you imply it but do not state it explicitly.  The same applies to the Region and Country structuring.  Can you clarify?

b) Why stop at 3 levels of hierarchy?  For example a city may be divided into suburban regions. Maybe there are also 8 suburban regions per city.  If this would be the case would it be possible to have one more extra bit - finally resulting in a /35 instead of a /36 as in your example?  And countries may be structured into continental regions - let's assume we have 8 of these too.   Here we need one extra bit too, finally resulting in a /34.   Generally the question is: is there some limit on the number of levels of hierarchy for which an "extra bit" may be used?

Many thanks and kind regards,
John

Dear colleagues,

We are pleased to announce that we have implemented policy proposal 2015-03, "Assessment Criteria for IPv6 Initial Allocation Size".

In accordance with the new policy, the criteria used to evaluate the size of an initial IPv6 allocations has been expanded to include:

  - Hierarchical and geographical structuring of the organisation
  - Planned longevity of the allocation
  - Segmentation of infrastructure for security

You can find more information about the expanded evaluation criteria here:
