Disclaimer: This guide focuses on a specific aspect of the Vultr BYOIP process, explaining how to assign a Vultr ASN to your leased subnet. For details on announcing the subnet, refer to the official Vultr BYOIP guide. 

Step 1: Lease a Subnet 

When leasing a subnet, please keep in mind that the smallest sized subnet that Vultr supports for BYIOP is a /24 subnet. 

Step 2: Access your leased IPs 

Following a successful lease, log in to the IPXO portal. Select “Lease” (1) and click “My Leased IPs” (2) from the dropdown menu. 

Step 3: Assign your leased subnet 

Find the subnet that you want to bring to Vultr and click “Assign” (3): 

In the “Add AS Organization” section, you will need to assign your own or Vultr AS number.  

This step is crucial as it allows Vultr to advertise your leased range using the ASN you provided. The Vultr AS number is AS20473. Type it in and click the “Add” button, which will become active. Alternatively, you can also add your own AS number. If you are adding your own ASN, its ownership must be verified by Vultr beforehand by following the procedure here.

Step 4: Confirming the ROA creation

Upon successfully creating the ROA record, you will receive a letter from the IPXO team. It usually takes up to 48 hours. 

Step 5: Follow Vultr BYOIP instructions

After receiving the ROA record confirmation letter, proceed further with the instructions on the Vultr BYOIP guide.
