Réseaux IP Européens Network Coordination Centre (RIPE NCC) is the regional internet registry (RIR) for Europe, the Middle East, and parts of Central Asia. They allocate and register blocks of Internet number resources to Internet service providers (ISPs) and other organizations. As RIPE ran out of available IPv4 blocks, companies now have to buy RIPE IP addresses on the secondary market. To acquire IP addresses, you will need a RIPE LIR account and knowledge of the RIPE region’s IPv4 transfer process.


By reading this helpful guide, you will come to understand why the world’s leading brands choose to work with IP Horizon for all their RIPE IP address needs.

RIPE IP transfer requirements

1- Creating a RIPE LIR account 

To acquire, manage, or buy RIPE IP addresses, you will need to register for a RIPE LIR account. RIPE has an easy 3-step process to create an account and add users to it. If you do not have an LIR account, you still have the option to create a contact record and have a sponsoring LIR.


- Registering an online account

An account with RIPE LIR allows you to manage different organizations, point of contact (POC) records, ASNs, and RIPE IP addresses. It is easy to register, and you can do so here.

- Create a point of contact (POC)

The personal point of contact record links directly to you and allows for the management of IP address resources and different organizations.


- Creating an Organization Identifier (Org-ID)

The Org-ID is tied to your company and is linked directly to your ASN, RIPE IP addresses, and POC records. RIPE may require a certificate of good standing in some cases to approve an Org-ID.

(1-2 weeks)

2- Buyer pre-approval

- RIPE has no pre-approval requirement to acquire a RIPE IPv4 address block unless the IPv4 block is transferred from ARIN or APNIC. This is referred to as an inter-RIR transfer.

- If a RIPE IPv4 transfer request is from ARIN or APNIC, the buyer will need to demonstrate at least 50% usage of the RIPE IPv4 addresses over five years. RIPE will request this information after ARIN or APNIC has approved the IPv4 transfer and sent their request to RIPE

3- RIPE IP address review

Once you have your LIR account, it is time to review a RIPE IP address block, verify the blacklist report, and review and sign the purchase agreement. Our team will provide you with a detailed blacklist report ensuring that the IP addresses are 100% clean before purchase. 


The following information is needed to send an IPv4 purchase agreement.


  • Legal entity name, and country

  • RIPE Org-ID
