How to Prepare Your Leased Subnet for AWS BYOIP

Follow this easy step-by-step guide and learn how to prepare the subnets you lease via the IPXO Marketplace for AWS BYOIP.

Follow this guide to learn how to assign Amazon ASN to your leased subnet and add the certificate. To learn how to retrieve the certificate, please refer to the official AWS BYOIP guide

Note: For a smoother process, have a certificate ready before doing the reassignment. If required, the certificate can be provided later on by contacting the IPXO support team. 

Step 1:  Access your leased IPs

Log in to the IPXO Portal and click My Resources (IPAM) -> My Leased IPs

Step 3:  Add the certificate

  1. Type in your company’s name in the Company name field. 
  2. In the Add AS Organization menu, you need to assign two Amazon AS numbers. This step is crucial as it allows Amazon to advertise your leased range. The two Amazon AS numbers are AS16509 and AS14618. Enter them separately and click Add on the right for each entry. The result should look like this:

If you perform the steps successfully, our support team will receive your request. Two ROAs and route objects will be created, and you will be updated via email once the request is completed. 

Once you receive a letter from the IPXO team notifying you about the successful ROA and route object creation, please proceed with the BYOIP AWS guide to onboard your leased subnet.
