These are taken from the FAQs link on RIPE NCC's website that I had shared
QWhat does RIPE NCC do with the address space that is returned?
A.When the RIPE NCC starts allocating address space from the last /8, all
IPv4 address space that is returned to the RIPE NCC will go back into the
last /8 pool of IPv4 address space. It will then be re-used to allocate
/22s to LIRs according to section 5.6 of “IPv4 Address Allocation and
Assignment Policies for the RIPE NCC Service
The rule 5.6 ( http://www.ripe.net/ripe/docs/ripe-553 )says:
5.6 Use of last /8 for PA Allocations
The following policies come into effect as soon as RIPE NCC is required to
make allocations from the final /8 it receives from the IANA. 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:
1. LIRs may only receive one allocation from this /8. The size of the
allocation made under this policy will be exactly one /22.
2. LIRs receive only one /22, even if their needs justify a larger
3. 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.
4. Allocations will only be made to LIRs if they have already
received an IPv6 allocation from an upstream LIR or the RIPE NCC.
2. Assignments to Internet Exchange Point
A /16 from the final /8 will be held in reserve for exclusive use by
Internet Exchange Points. On application for IPv4 resources, an Internet
Exchange Point (IXP) will receive one number resource (/24 to /22)
according to the following:
- This space will be used to run an Internet Exchange Point peering LAN;
other uses are forbidden.
- Organisations receiving space under this policy must be Internet
Exchange Points and must meet the definition as described in
section two of
the RIPE document “IPv6 Address Space for Internet Exchange Points”.
- IXPs holding other PI IPv4 space for their peering LAN (i.e. they
are seeking a larger assignment), must return their old peering LAN
resources back to this pool within 180 days of assignment.
- New Internet Exchange points will be assigned a /24. Internet
exchange points may return this /24 (or existing PI used as an
LAN) should they run out of space and receive a larger (/23, or /22 if
utilisation requires) assignment.
- IP space returned by Internet Exchange Points will be added to the
reserved pool maintained for Internet Exchange Point use.
- Assignments will only be made to IXPs who have already applied for,
or received an IPv6 assignment for their peering LAN
3. Unforeseen circumstance
1. 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
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
has been distributed, it returns to the pool to be distributed as per
4. Post-depletion Address Recycling
This section only applies to address space that is returned to the RIPE
NCC and that will not be returned to the IANA but re-issued by the RIPE NCC
1. Any address space that is returned to the RIPE NCC will be covered by
the same rules as the address space intended in clause 1.
2. Minimum allocation sizes for the relevant /8 blocks will be
updated if necessary
5. Insufficient address space
In case an allocation of a single /22 as per clause 1 can no longer be
made, multiple allocations up to an equivalent of a /22 in address space
will be made to fulfill a request.
