5.1.1. Initial allocation criteria
5.1.1. Initial allocation criteria for LIRs
To qualify for an initial allocation of IPv6 address space, an organisation must:
To qualify for an initial allocation of IPv6 address space, an LIR must have a plan for making sub-allocations to other organisations and/or End Site assignments within two years.
a) be an LIR;
b) have a plan for making sub-allocations to other organisations and/or End Site assignments within two years.
5.1.2. Initial allocation size
5.1.2. Initial allocation size
Organisations that meet the initial allocation criteria are eligible to receive an initial allocation of /32. For allocations up to /29 no additional documentation is necessary.
LIRs that meet the initial allocation criteria are eligible to receive an initial allocation of /32 up to /29 without needing to supply any additional documentation.
Organisations may qualify for an initial allocation greater than /29 by submitting documentation that reasonably justifies the request. If so, the allocation size will be based on the number of users, the extent of the organisation's infrastructure, the hierarchical and geographical structuring of the organisation, the segmentation of infrastructure for security and the planned longevity of the allocation.

Organisations that hold an existing IPv6 allocation may receive a subsequent allocation in accordance with the following policies.

Subsequent allocation will be provided when an organisation (i.e. ISP/LIR):
S Subsequent allocation will be provided when an LIR:
a) Satisfies the evaluation threshold of past address utilisation in terms of the number of sites in units of /56. To this end, the HD-Ratio [RFC 3194] is used to determine the utilisation thresholds.

b) Can justify new needs (which can't be satisfied within the previous allocation), according to the initial allocation size criteria as described in section 5.1.2.

5.2.3. Subsequent allocation size
5.2.3. Subsequent allocation size
When an organisation meets the subsequent allocation criteria, it is immediately eligible to obtain an additional allocation that results in a doubling of the address space allocated to it. Where possible, the allocation will be made from an adjacent address block, meaning that its existing allocation is extended by one bit to the left.

If an organisation needs more address space, it must provide documentation justifying its new requirements, as described in section 5.1.2. The allocation made will be based on the relevant documentation.

5.3. LIR-to-ISP allocation
5.3. LIR-to-ISP allocation
There is no specific policy for an organisation (LIR) to allocate address space to subordinate ISPs. Each LIR organisation may develop its own policy for subordinate ISPs to encourage optimum utilisation of the total address block allocated to the LIR. However, all /48 assignments to End Sites are required to be registered either by the LIR or its subordinate ISPs in such a way that the RIR/NIR can properly evaluate the HD-Ratio when a subsequent allocation becomes necessary.

5.4.3. Assignment to operator's infrastructure
An organisation (i.e. ISP/LIR) may assign a network prefix per PoP as the service infrastructure of an IPv6 service operator. Each assignment to a PoP is regarded as one assignment regardless of the number of users using the PoP. A separate assignment can be obtained for the in-house operations of the operator.

5.5 Registration
5.5 Registration
When an organisation holding an IPv6 address allocation makes IPv6 address assignments, it must register these assignments in the appropriate RIR database.

5.6. Reverse lookup
5.6. Reverse lookup
When an RIR/NIR delegates IPv6 address space to an organisation, it also delegates the responsibility to manage the reverse lookup zone that corresponds to the allocated IPv6 address space. Each organisation should properly manage its reverse lookup zone. When making an address assignment, the organisation must delegate to an assignee organisation, upon request, the responsibility to manage the reverse lookup zone that corresponds to the assigned address.

10. Appendix A: HD-Ratio
Thus, the utilisation threshold for an organisation requesting subsequent allocation of IPv6 address block is specified as a function of the prefix size and target HD ratio. This utilisation refers to the use of /56s as an efficiency measurement unit, and does not refer to the utilisation of addresses within those End Sites. It is an address allocation utilisation ratio and not an address assignment utilisation ratio.
