Address space may only be re-allocated to another lir that is also a member of the ripe ncc. The block that is to be re-allocated must not be smaller than the minimum allocation block size at the time of re-allocation. An lir may only receive a transferred allocation after their need is evaluated and approved by the ripe ncc, following the policies set for receiving further allocations within ripe region (see the section.3 Additional Allocations of this document). Re-allocation must be reflected in the ripe database. This re-allocation may be on either a permanent or non-permanent basis. Lirs that receive a re-allocation from another lir cannot re-allocate complete or partial blocks of the same address space to another lir within 24 months of receiving the re-allocation. The ripe ncc will record the change of allocation after the transfer. Please note that the lir always remains responsible for the entire allocation it receives from the ripe ncc until the transfer of address space to another lir is completed or the address space is returned.

Lirs should note that evaluating a request for an allocation is different from evaluating a request for an assignment. With assignments, the evaluator can see the network plans for a single organisation. With allocations, the evaluator is often presented with sales and marketing plans. The addressing requirements of plan individual organisations cannot be examined. It is recommended that lirs make use of a slow-start mechanism when making a sub-allocation for a downstream network operator. There are two main advantages to this: the lir can ensure that the address space it sub-allocates is used efficiently; also the lir can determine the ability of the downstream organisation to operate within the policies set by the ripe community. Sub-allocations form part of an lir's aggregatable address space. As such, an lir may want to ensure that the address space is not retained by a downstream network if the downstream network operator ceases to receive connectivity from the lir's network. Lirs not wishing to lose address space in this way are responsible for ensuring that the status of the sub-allocation is clear in any contracts between the lir and the downstream network operator. 5.5 Transfers of Allocations Any lir is allowed to re-allocate complete or partial blocks of ipv4 address space that were previously allocated to them by either the ripe ncc or the iana. Such address space must not contain any block that is assigned to an End User.
This is the smallest prefix length that can be reverse delegated and allows for a reasonable number of small assignments to be made by a downstream network operator. An lir may sub-allocate up to an ipv4 /20 (4096 addresses) to a downstream network operator every twelve months. Lirs may make sub-allocations to multiple downstream network operators. However, downstream network operators may receive sub-allocations totalling more than a /20 from more than one lir. The lir is contractually responsible for ensuring the address space allocated to it is used in accordance with the ripe community's policies. It is recommended that lirs have contracts requiring downstream network operators to follow the ripe community's policies when those operators have sub-allocations. The ripe ncc considers sub-allocated space as used when evaluating requests from the lir for an additional ipv4 allocation. Where an lir has made many sub-allocations with little assigned within them, the ripe ncc will ask the lir to justify the reasons for the sub-allocations.
The ripe ncc will do its best to allocate contiguous address space in order to support aggregation. This cannot be guaranteed as it depends on factors outside the ripe ncc's influence (e.g. The number of new lirs and the time needed to utilise the allocation). 5.4 Sub-allocations Sub-allocations are intended to aid the goal of routing aggregation and can only be made from allocations with a status of allocated. Lirs holding allocated pi or allocated unspecified allocations may be able to convert them to pa allocations if professional there are no assigned pi networks within. The meanings resumes of the various status: attribute values are described in Section.0. Lirs wishing to convert their allocations to pa status should contact the ripe ncc by email at lir-help _at_ ripe _dot_ net. The minimum size of a sub-allocation is /24.
The size of future allocations is based on the usage rate of previous allocation(s). 5.3 Additional Allocations An lir may receive an additional allocation when about eighty percent (80) of all the address space currently allocated to it is used in valid assignments or sub-allocations. A new allocation can be made if a single assignment or sub-allocation requires a larger set of addresses than can be satisfied with the address space currently held by the lir. Reservations are not considered valid assignments or sub-allocations. It may be useful for internal aggregation to keep some address space free for future growth in addition to the actual assignment. However, the lir must be aware that these internal reservations are not counted as valid usage. The space must be sub-allocated or assigned before the lir can request another allocation. To obtain a new allocation, an lir should submit a request to the ripe ncc using the "IPv4 Additional Allocation Request Form" available from the ripe document Store at: t/ripe/docs/add-allocation Additional address space will only be allocated after the information supplied with the request has.

5.0 Policies and guidelines for Allocations An allocation is a block of ipv4 addresses from which assignments are reviews taken. The ripe ncc allocates enough address space to lirs to meet their needs for a period essay of up to 12 months. Starting on, a gradual reduction in the allocation period will be applied as follows: As of, the ripe ncc will start allocating enough address space to lirs to meet their needs for a period of up to nine months. As of, the ripe ncc will start allocating enough address space to lirs to meet their needs for a period of up to six months. As of, the ripe ncc will start allocating enough address space to lirs to meet their needs for a period of up to three months.
All lirs receiving address space from the ripe ncc must adopt a set of policies that are consistent with the policies formulated by the ripe community and described in this document. 5.1 First Allocation The ripe ncc's minimum allocation size is /21. Details of how to join the ripe ncc can be found in the ripe document " Procedure for Becoming a member of the ripe ncc " Members can receive an initial ipv4 allocation when they have demonstrated a need for ipv4 address space. 5.2 Slow-start Mechanism The slow-start mechanism was put into place to ensure a consistent and fair policy for all lirs with respect to allocations. Address space is allocated to lirs at the rate that the addresses are sub-allocated and assigned by the lirs. An allocation larger than the minimum size can be made if a need is demonstrated.
To maximise the lifetime of the public ipv4 address space, addresses must be distributed according to need, and stockpiling must be prevented. Registration: The provision of a public registry documenting address space allocations and assignments must exist. This is necessary to ensure uniqueness and to provide information for Internet troubleshooting at all levels. 3.1 Confidentiality Internet Registries (IRs) have a duty of confidentiality to their registrants. Information passed to an ir must be securely stored and should not be distributed wider than necessary within the. When necessary, the information may be passed to a higher-level ir under the same conditions of confidentiality.
3.2 Language Please note that all communication with the ripe ncc must be in English. 4.0 Registration Requirements All assignments and allocations must be registered in the ripe database. This is necessary to ensure uniqueness and to support network operations. Only allocations and assignments registered in the ripe database are considered valid. Registration of objects in the database is the final step in making an allocation or assignment. Registration data (range, contact information, status etc.) must be correct at all times (i.e. They have to be maintained).

These are described in rfc 3330 and are beyond the scope of this document. Rfc 3330 can be found at: ftp:t/rfc/rfc3330.txt.0 goals of the Internet Registry system Public ipv4 address assignments should be made with the following goals in mind: Uniqueness: Each public ipv4 address worldwide must be unique. This is an absolute requirement guaranteeing that every host on the Internet can be uniquely identified. Aggregation: Distributing ipv4 addresses in an hierarchical manner permits the aggregation of routing information. This helps to ensure proper operation of Internet routing. Conservation: Public ipv4 address space must be fairly distributed to the End Users operating networks.
The ripe community's policies for asn assignment and ipv6 are published in the ripe document Store at: t/ripe/docs/policy.0 ipv4 Address Space essay for the purposes of this document, ip addresses are 32-bit binary numbers used as addresses in the ipv4 protocol. There are three main types of ipv4 addresses: Public ip addresses are assigned to be globally unique according to the goals described in Section 3 of this document. Some address ranges are set aside for the operation of private ip networks. Anyone may use these addresses in their private networks without registration or co-ordination. Hosts using these addresses cannot directly be reached from the Internet. Such connectivity is enabled by using the technique known as Network Address Translation (NAT). Private addresses restrict a network so that its hosts only have partial Internet connectivity. Where full Internet connectivity is needed, unique, public addresses should be used.
and Central Asia. The ripe ncc is responsible for the allocation and assignment of Internet Protocol (IP) address space, autonomous System Numbers (ASNs) and the management of reverse domain names within this region. The distribution of ip space follows the hierarchical scheme described in the document " Internet Registry system ". 1.1 Scope This document describes the policies for the responsible management of globally unique ipv4 Internet address space in the ripe ncc service region. The policies documented here apply to all ipv4 address space allocated and assigned by the ripe ncc. These policies must be implemented by all ripe ncc member lirs. This document does not describe policies related to as numbers, ipv6, multicast, or private address space. Nor does it describe address distribution policies used by other rirs.
This document describes the ripe community's current ipv4 address allocation and assignment policies. They were developed through a bottom-up, consensus driven, open policy development process in the ripe address Policy working Group (ap wg). The ripe network coordination Centre (ripe ncc) facilitates and supports this process. These policies apply to the ripe ncc and the local Internet Registries (LIRs) within the ripe ncc service region.
