Inter-RIR Transfers
Inter-RIR Transfers are transfers that take place when the source and the destination organization are not part of the same service region.
Inter-RIR Transfers are transfers that take place when the source and the destination organization are not part of the same service region.
Each registry has its own policy and there are differences in requirements around processing Inter-RIR transfers. For the most part, all of the participating registries support transfers of IPv4 address space and autonomous system numbers (ASN), including legacy. Inter-RIR transfers take longer to complete because of the manual processing and collaboration requirement between RIRs involved with completing them. Whether you are looking to buy or sell across regions, Prefixx manages the entire cross-registry process.
No action required from the recipient side until the source RIR is ready to process the transfer. As soon as the source has determined that a block is eligible for out-of-RIR transfer, they will contact the destination RIR for the next part of the process. The destination RIR will contact the recipient LIR for more information. RIPE does not charge any transfer fees.
RIPE TransfersSimilar to the RIPE NCC process, APNIC does not require action from the recipient. Once APNIC is ready to proceed, they will contact the destination RIR, who will reach out to the recipient for further information and preapproval. Inter-RIR transfers with APNIC are however subject to other policies and fees, especially when transferring to NIRs (National Internet Registries). The fee may differ per NIR, for more information about transfer fees, please visit APNIC NIR IPv4 Transfer
APNIC Transfers
Much like every other form of transfer with ARIN, you will need an RSA and (if receiving) pre-approval ticket in order to proceed. Both recipients and senders of an Inter-RIR transfer are also obligated to pay a $500 transfer fee. Legacy resource holders will need to sign an RSA prior to initiating any transfer process.
ARIN TransfersLACNIC Inter-RIR transfers follow a similar policy to APNIC's. The main difference is their fee structure, which is higher for Inter-RIR transfers at $1,000 for anything smaller than a /19 and $1,500 for anything larger than a /19. A non-refundable deposit of $200 is required before any request will be reviewed. LACNIC Inter-RIR transfers usually take longer to complete.
An inter-RIR transfer is the movement of IPv4 address space between organizations registered in different Regional Internet Registry (RIR) service regions. For example, transferring a block from a RIPE NCC member to an ARIN organization.
ARIN, RIPE NCC, APNIC, and LACNIC all support inter-RIR transfers. Each registry has its own policy and requirements. AFRINIC does not currently participate in inter-RIR transfers.
Inter-RIR transfers typically take 4-8 weeks to complete, which is longer than intra-region transfers due to the coordination required between two different registries. Processing times vary depending on the registries involved and the complexity of the transaction.
Yes. Most registries charge transfer fees for inter-RIR transactions. ARIN charges $500 for both the sender and receiver. LACNIC charges $1,000-$1,500 depending on block size, plus a $200 non-refundable deposit. RIPE NCC does not charge transfer fees.
Yes, legacy blocks can be transferred between RIRs, but additional steps may be required. For example, ARIN requires legacy resource holders to sign a Registration Services Agreement (RSA) before initiating any transfer. Prefixx has extensive experience with legacy block transfers across all regions.
