[sig-policy] Further information re Prop-083 from ARIN's ppml list - 1
Below I have a reply from David Farmer, an ARIN member who has a proposal discussion ongoing at the moment who I thought were discussing the same kind of proposal, but they're actually discussing something a little different.
But they have included information that basically states that ARIN has had a proposal basically the same, and has adopted it last year.
Below are the links to their proposal - 2009-5 and the details of implementation into their NRPM.

Thanks for the pointer.
But, this sounds more like ARIN 2009-5: IPv6 Multiple Discrete Networks
to me.
https://www.arin.net/policy/proposals/2009_5.html
This was just implemented into ARIN's NRPM.
https://www.arin.net/policy/nrpm.html#six_11
The intent of my question is how do we want to deal with networks that
are not connected to the Internet. In other words, networks that have
no intention of achieving global reachability but still many need or
want globally unique addresses. ARIN specifically addresses a special
case of what I am asking about in 6.10.2 Micro Allocation for Internal
Infrastructure. Also, by the fact that current end-user assignments are
based on IPv4 Policy, then section 4.3.5. Non-connected Networks allows
such networks to get an IPv6 assignment.
But, I believe we need to address this issue much more directly and
cleanly than in current policy.

This is due to that even if an LIR could de-aggregate its /32 to say, 8 /35's or 16 36's, these entries in the routing table would have the exact same result as if they had 16 * /32's.

> 1. Introduction
> ----------------
>
> This is a proposal to enable current APNIC account holders with existing
> IPv6 allocations to receive subsequent IPv6 allocations from APNIC for
> use in networks that are not connected to the initial IPv6 allocation.
>
>
> 2. Summary of current problem
> ------------------------------
>
> An APNIC account holder with an existing /32 IPv6 allocation (or larger)
> is unable to deaggregate that allocation into routes smaller than a /32
> due to the community practice of 'filter blocking' or 'bogon lists'
> associated with RIR blocks which are known to have a minimum allocation
> size of /32 [1].
>
> An LIR may want to build a network in a separate location and provide
> IPv6 connectivity; however, because the LIR risks routability problems
> if they deaggregate, they cannot use a subset of their initial
> allocation in the new location.
>
> For example:
>
> An ISP has a /32 allocation which they announce via an upstream
> in New Zealand. The ISP wants to build a new network in Singapore.
> The ISP's new network in Singapore is not connected to the existing
> New Zealand network and the ISP is using a local transit provider
> to obtain dual stacked connectivity.
>
> If the network was using IPv4 addresses, the ISP would usually
> be able to deaggregate their allocation and announce one part of
> the deaggregated range to the local transit provider.
>
> In IPv6, however, this is not possible due to 'community filtering'
> on ranges smaller than a /32.
>
> Such a filter may look like the following:
>
> ipv6 prefix-list ipv6-ebgp-strict permit 2400::/12 ge 19 le 32
>
> This above statement in the IPv6 BGP filter recommendations would
> cause any announcements by an ISP which had an allocation,
> such as 2400:0000::/32, to announce smaller routes from that block,
> such as multiple /35s for example, to be filtered. In a default
> free situation, connectivity to the ISP would be problematic.
>
> Instead, the ISP needs to obtain a new /32 allocation to be able to
> have IPv6 connectivity in the new location with an independent
> (from their primary network) transit provider.

> 3. Situation in other RIRs
> ---------------------------
>
> AfriNIC, ARIN, LACNIC and RIPE currently have no similar policies or
> proposals. However, ARIN mailing lists are presently discussing this
> situation and there seems to be significant support.

> 4. Details of the proposal
> ---------------------------
>
> 4.1 It is proposed that alternative criteria be added to the subsequent
> IPv6 allocation policy [2] to allow current APNIC account holders
> with networks in multiple locations but without a connecting
> infrastructure to obtain IPv6 resources for each location.
>
> 4.2 To qualify for subsequent IPv6 allocations under the proposed
> alternative criteria, account holders must:
>
> - Be a current APNIC account holder with an existing IPv6
> allocation
> - Be announcing its existing IPv6 allocation
> - Demonstrate that the LIR has additional networks that are not
> connected to the network announcing its existing IPv6 allocation
>
>
> 5. Advantages and disadvantages of the proposal
> ------------------------------------------------
>
> 5.1 Advantages
>
> - This proposal enables current APNIC account holders to avoid
> problematic network design issues and policy issues related to
> deaggregation.
>
> - Current APNIC account holders will be able to acquire resources
> and announce them separately to transit providers in disparate
> locations.
>
>
> 5.2 Disadvantages
>
> - This proposal could cause faster consumption of IPv6 address
> space. However, given the size of the total IPv6 pool, the author
> of this proposal does not see this as a significant issue.
>
>
> 6. Effect on APNIC members
> ---------------------------
>
> APNIC members would be able to build networks in separate locations and
> obtain local IPv6 connectivity and announce their own resources.
>
>
> 7. Effect on NIRs
> ------------------
>
> The proposal allows for NIRs to have the choice as to when to adopt this
> policy for their members.
