Subnet Ownership Confirmation

Learn how to validate your subnet ownership.

Subnet ownership confirmation is proof that you are the legitimate owner of the IP addresses and that the subnet has been issued to you. The confirmation of the subnet is mandatory.

Follow the guides below to learn how to validate subnet ownership for subnets from every Regional Internet Registry:

How to receive the ownership confirmation email for AFRINIC subnets

To receive a subnet confirmation ownership email for AFRINIC subnets, you must set the abuse-mailbox contact for either admin-c or tech-c role (as maintainer, mnt-by). Before you add the abuse-mailbox contact to your maintainer, check if your subnet status is acceptable at IPXO. 

What are acceptable ARFRINIC subnets? 

Use the Adding Subnets to IPXO From AFRINIC guide to learn which subnet statuses are accepted in the IPXO Marketplace. The information can help you avoid problems when moving your subnet to the IPXO Marketplace in the future. 

How to find your maintainer admin-c or tech-c in AFRINIC

The subnet ownership confirmation email for AFRINIC subnets is sent to your admin-c or tech-c abuse-mailbox contact when the subnet is added to the IPXO Marketplace.  

To demonstrate, we search IPXO-MNT (our maintainer) using AFRINIC’s Whois Search query tool.

IPXO-MNT entered in the AFRINIC search query tool.

In this example, the admin-c attribute has the abuse-mailbox contact associated with it.

Note: You must set abuse-mailbox to at least one of the maintainers (admin-c or tech-c).
