Transfer FAQs

Show or Hide answer Do I need to be a member of the RIPE NCC to receive an IPv4 or IPv6 transfer?

It depends on what kind of address space is being transferred.

The receiving organisation will need to be a member in the case of:

  • A transfer of allocated Provider Aggregatable (PA) IPv4 or allocated IPv6 space from another LIR
  • A transfer of IPv4 PA or IPv6 allocated space through a merger or acquisition (though the receiving party may become a member as the transfer is processed)


The receiving organisation will not need to be a member in the case of:

  • A transfer of Provider Independent (PI) space from another resource holder
  • A merger or acquisition where the organisation receiving PI space has a sponsoring LIR
Show or Hide answer Can Provider Independent (PI) space be transferred?

Yes, Provider Independent (PI) IPv4 and IPv6 space can be transferred according to:


Additionally, in the case of a merger or acquisition, the registration of these resources can be updated to reflect the new holder. This is explained further in the Mergers and Acquisitions section.

Show or Hide answer What are the time restrictions when transferring Internet number resources?

IPv4 addresses can only be transferred if 24 months have elapsed since:

  • The allocation was made by the RIPE NCC
  • The address space was received by another entity

There are no time constraints for transferring IPv6 or ASNs.

Show or Hide answer What is the minimum size of an IPv6 block that can be transferred?

In accordance with "IPv6 Address Allocation and Assignment Policy":

  • For IPv6 allocations, the block that is to be re-allocated must not be smaller than the minimum allocation size at the time of re-allocation (currently /32)
  • For IPv6 PI assignments, the block that is to be re-assigned must not be smaller than the minimum assignment block size at the time of re-assignment (currently /48)
Show or Hide answer Do I need to be a member of the RIPE NCC to receive an ASN transfer?

No. The receiving organisation can either be:

Show or Hide answer Can I transfer Internet number resources in/out of the RIPE NCC service region?

The "Policy for Inter-RIR Transfers of IPv4 Address Space" has been implemented by the RIPE NCC. This means it is possible to transfer Internet number resources to/from other RIR service regions with corresponding inter-RIR transfer policies. Currently this is APNIC and ARIN.

Show or Hide answer How can I find someone offering/seeking IPv4 address space?

It is up to LIRs and/or End Users to arrange their own transfers. However, for transfers of allocated PA space, the RIPE NCC has developed a listing service for members to advertise the IPv4 resources they are offering/seeking.

LIRs are under no obligation to use the service, and may arrange transfers independently.

Show or Hide answer How long will it take to approve a transfer?

It is difficult to give an exact timeframe, as it will depend on the type of transfer and the amount of additional documentation required. However, we will do our best to process any transfers as soon as possible.

Show or Hide answer Is there a cost for processing a transfer?

No. The RIPE NCC processes transfers as a service to its members.

Show or Hide answer I have questions about legacy space, who can I contact?

If you have any questions about transferring or registering legacy space, you can call +31 20 535 4444 or email legacy@ripe.net.

Show or Hide answer Can I transfer Provider Independent (PI) space that currently is not registered with a sponsoring LIR?

No. A transfer of Provider Independent (PI) space can take place only if both the offering and receiving party fulfil the contractual requirements for independent resources.

Show or Hide answer Can I buy or sell IPv4 address space?

Yes. RIPE Policies use the term "transfer", but this can include any agreement to buy or sell address space.

The RIPE NCC has no role to play in any financial agreement between members.

Show or Hide answer Do restrictions that apply to transfers within the RIPE NCC service region (such as the 24-month holding period) also apply to inter-RIR transfers?

Yes. RIPE Policies apply for as long as an Internet number resource is registered in the RIPE Registry and regardless of the direction of an inter-RIR transfer.

Show or Hide answer Can I request an inter-RIR transfer to/from LACNIC or AFRINIC?

No. Inter-RIR transfers are only possible between RIRs with compatible policies. Currently, ARIN and APNIC are the only RIRs that can perform inter-RIR transfers with the RIPE NCC.

Show or Hide answer What status will my resources receive when they are transferred to another RIR?

IPv4 PA allocations, IPv4 PI assignments, AS Numbers and legacy resources transferred from the RIPE NCC service region to another RIR will receive the status defined by the policies and contracts of the receiving RIR.

Show or Hide answer I want to receive a transfer of resources from another RIR. How will their status be determined?

For IPv4 addresses:

  • If the receiving party is a member of the RIPE NCC, the possible “status:” values are “ALLOCATED PA” or “ASSIGNED PI”.
  • If the receiving party is an End User that has a contract with a sponsoring LIR, the IPv4 space will be imported in the RIPE Registry as “ASSIGNED PI”.

AS Numbers will receive the status “ASSIGNED”.

Legacy resources (IPv4 and AS Numbers) that are transferred to the RIPE NCC service region, and have not had their legacy status revoked by the transferring RIR, will be treated as legacy according to RIPE Policy and will retain their “LEGACY” status unless otherwise requested by the receiving party.

Show or Hide answer How long will it take for an inter-RIR transfer to be completed?

The RIPE NCC cannot give an exact timeframe for an inter-RIR transfer to be completed. Inter-RIR transfers require considerably more work than regular transfers. Coordination between the RIRs (in different time zones) is required to ensure compliance with relevant policies in both regions, and updates to the RIR registries must be synchronised to ensure correct registration. Because of this, processing transfers between RIRs will take longer than transfers within the RIPE NCC service region.

Show or Hide answer Does a broker need to be a member of the RIPE NCC?

No, any legal entity or natural person can become a Recognised IPv4 Transfer Broker by signing the "Recognised IPv4 Transfer Broker Agreement" and providing their registration papers. In doing so, the broker agrees to adhere to the relevant RIPE Policies and RIPE NCC procedural documents.

Show or Hide answer How do I become a Recognised IPv4 Transfer Broker?

Email ncc@ripe.net and we will ask you to sign the “Recognised IPv4 Transfer Broker Agreement”, and provide a copy your registration papers and the contact details that will be shown in the list of IPv4 Transfer Brokers.

By becoming a Recognised IPv4 Transfer Broker, you agree to adhere to the relevant RIPE Policies and RIPE NCC procedural documents.

Show or Hide answer What is the requirement to become a Recognised IPv4 Transfer Broker?

There are no costs to be involving in becoming a Recognised IPv4 Transfer Broker.  However, you will need to agree to adhere to the relevant RIPE Policies and RIPE NCC procedural documents.

Show or Hide answer Besides contacting a broker, is there any other way to find or advertise IPv4 address space?

Yes, as a member of the RIPE NCC you can also make use of the IPv4 Transfer Listing Service. This is a platform that enables RIPE NCC members to list and exchange IPv4 address space they no longer need. The listing service is only available to members and its use is included in the annual RIPE NCC membership fee.

Show or Hide answer What terms and conditions apply to the IPv4 address space I may receive from a broker?

The IPv4 transfer request will be evaluated according to “IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region”.

The RIPE NCC procedural document “Transfer of Internet Number Resources and Change of a Member’s Official Legal Name” describes the process that the RIPE NCC will follow for any transfer request.

Brokers need to adhere to the relevant RIPE Policies and RIPE procedural documents at all times.

Show or Hide answer Do brokers need to be registered with the RIPE NCC to arrange transfers?

No. Brokers that are not listed as Recognised IPv4 Transfer Brokers are still able to facilitate transfers in the RIPE NCC service region.

It is important also to note that recognised brokers are not endorsed by the RIPE NCC, do not act on our behalf, and do not receive any privileged information regarding our members or Internet number resources within our service region. 

Show or Hide answer Can I transfer resources between the multiple LIR accounts that I hold?

Yes, you can. However, you should take the following into account:

  • IPv4 allocations are subject to the RIPE NCC Transfer Policy and can therefore only be transferred 24 months after the allocation date.
  • If after such a transfer you decide to close the LIR account, the full annual fee for the closing LIR account must be paid. If there is only one last IPv4 allocation left in the LIR account, the annual fee needs to be paid before that resource can be transferred.
