Requirements for Bring Your Own IP (BYOIP) and Bring Your Own ASN (BYOASN)

This article explains which requirements you must fulfil as part of the Bring Your Own IP (BYOIP) and Bring Your Own ASN (BYOASN) services at IONOS. This includes how to properly configure and secure your IP addresses and Autonomous System Numbers. This article explains how you fulfil the requirements specified in the approval letter. Download the approval letter here.

With Bring Your Own IP (BYOIP), you can use your own public IP addresses in the Private Cloud. In this way, you can ensure uninterrupted connectivity for your company if, for example, you migrate your services to the IONOS Public Cloud. This is especially true if you have created architecture dependencies with specific IP addresses. You remain the owner of these IP addresses.

In addition, you can maintain the established reputation of your IP addresses when using BYOIP. In this way, the email addresses used will remain on the whitelists of anti-spam applications.

If you have any questions or require further support, please contact IONOS Cloud Support. The contact information can be found on the following page:

First, log in to your IRR database account (e.g. RIPE NCC, ARIN, etc.) with your user name and password. This will give you access to the various areas of the IRR database where you can manage your IP address ranges, Route Objects, and RPKI-ROAs (Resource Public Key Infrastructure - Route Origin Authorizations).

• In the IRR database, navigate to the IP address range registration section.

• Ensure that your IP address range is correctly registered and up-to-date by checking the following information:
  
  IP address range: The IP address range must be correctly listed including the start and end IP address.
  Origin AS (Autonomous System): The originating AS must be listed as AS8560 (IONOS) for BYOIP, or as your own autonomous system number (ASN) for BYOASN. 
  Route Object: A Route Object must be present and correctly configured for your IP address range.

• Make any necessary updates to your IP address range registration, e.g. update the IP address range or the source ASN.

• In the same IRR database, navigate to the section for creating route objects.
• Create a new Route Object for your IP address range using the correct source AS (AS8560 for BYOIP, or your own ASN for BYOASN).
• Make sure that the route object is formatted correctly and contains all the required information. Examples:
  
  IP address range: The IP address range must be listed correctly, including the start and end IP address.
  Origin AS: The origin AS must be listed as AS8560 (IONOS) for BYOIP or as your own autonomous system number (ASN) for BYOASN. 
  AS-SET: The AS-SET must be listed correctly if applicable.
• Ensure that route objects already created are correct and remain up to date by checking and updating them.

• In the same IRR database, navigate to the RPKI ROA creation section.
• Create a new RPKI ROA for your IP address range using the correct prefix lengths and origin AS (AS8560 for BYOIP, or your own ASN for BYOASN).
• Make sure that the RPKI-ROA is formatted correctly and contains all the necessary information. Examples:
  
  IP address range: The IP address range must be listed correctly, including the start and end IP address.
  Prefix length: The length of the prefix must be specified correctly.
  Origin AS: The origin AS must be listed as AS8560 (IONOS) for BYOIP, or as your own Autonomous System Number (ASN) for BYOASN.
• Ensure that any RPKI ROAs already created are correct and up-to-date by checking and updating them.
  
   

• If you are using BYOASN, navigate to the AUTNUM object for your Autonomous System Number in the IRR database.
• Check the RPSL policy to ensure that AS8560 (IONOS) is authorised as the upstream of your Autonomous System.
• Check the following information:
  
  AS-SET: The AS-SET must be listed correctly.
  Upstream AS: AS8560 (IONOS) must be listed correctly as upstream AS.
• Make any necessary updates to the RPSL policy to ensure that AS8560 (IONOS) is authorised as an upstream of your Autonomous System.

By following the steps listed here, you can ensure that your IP addresses and ASNs are properly configured and secured, and that you fulfil the requirements specified in the approval letter.
