DRAFT: IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region
[Following text is to appear in the RIPE Policy document, IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region (ripe-492) if the proposal reaches consensus.]
Use of last /8
When the total remaining space in the unallocated RIPE NCC address pool reaches a threshold of a total of one /8, following policies will come in place and from then on, the distribution of IPv4 address space will only be done as follows:
1. Allocations for LIRs from the last /8
On application for IPv4 resources LIRs will receive IPv4 addresses according to the following:
- LIRs may only receive one allocation from this /8. The size of the allocation made under this policy will be no larger than a /22.
- LIRs receive at most a /22, even if their needs justify a larger allocation.
- LIRs may apply for and receive this allocation once they meet the criteria to receive IPv4 address space according to the allocation policy in effect in the RIPE NCC service region at the time of application.
- Allocations will only be made to LIRs if they have already received an IPv6 allocation from an upstream LIR or the RIPE NCC.
2. Unforeseen circumstances
A /16 will be held in reserve for some future uses, as yet unforeseen.
The Internet is a disruptive technology and we cannot predict what might happen. Therefore it is prudent to keep a /16 in reserve, just in case some future requirement makes a demand of it.
In the event that this /16 remains unused at the time the remaining /8 covered by this policy has been distributed, it returns to the pool to be distributed as per clause 1.
