Adding Subnets to IPXO From RIPE

What are the requirements for adding RIPE-NCC allocated subnets to the IPXO Marketplace?

IPXO is a fully automated IP address lease and monetization platform. To get the most out of it, make sure to get acquainted with the minimum requirements for listing RIPE NCC-issued subnets.

Check the subnet’s Whois information

Make sure the inetnum you are adding exists in RIPE’s Whois database. Use the RIPE Database query search tool to look this information up.

Authorize IPXO to manage the subnet

IPXO supports two types of authorization for RIPE NCC allocated IP addresses:

  • mnt-by: Set IPXO-MNT as the maintainer in the RIPE NCC portal for a given inetnum (the recommended method)
  • ROA: Use this method when adding a /24 Allocated PA subnet by issuing a non-specific ROA for a given subnet with ASN: 834 (no other ROAs should exist) and adding IPXO-MNT as mnt-lower, mnt-domains, mnt-routes

Check if the subnet’s status is accepted

Based on the Inetnum Status, perform the required action from the following table:

Inetnum StatusAction
Sub-allocated PAAuthorize by adding IPXO-MNT as mnt-by
LegacyUnsupported
Allocated PA
(mask = 24)
Authorize via ROA and by adding IPXO-MNT as mnt-lower, mnt-domains, mnt-routes
Assigned PAUnsupported: Recreate the inetnum with a Sub-Allocated PA status
Allocated PA
(mask < 24)
Create a more specific inetnum with Sub-Allocated PA status and add IPXO-MNT as mnt-by
Assigned PIUnsupported: Here is an official guide from RIPE on how to convert an Assigned PI to an Allocated PA
