Purpose

To better support our customers with restricted networks requiring a set list of IP addresses to be allowed, VMware now supports IP Limited Content Distribution Network (CDN) capabilities. More details on the benefits of the CDN solution can be found here.

Impact / Risks

While CDN integration optimizes the delivery of large applications to end-user devices, the default CDN delivery method requires devices to be in an open network. As a result, customers working behind restricted networks have not been able to benefit from this feature historically.

Resolution

The IP Limited CDN solution delivers content through a specific set of anycast IP addresses. This is ideal for customers whose end-users are on restricted networks where traffic must be locked down to only required IP addresses. For further information on how it works, please refer to Akamai’s Edge IP binding article.

To extend service to all regions, we will be changing the current set of IP addresses to the ones in bold below.  Instead of specifying per country, it will be divided into geographical regions instead. You will only need to set the allowed list according to the region your UEM environment is located in. If you are already utilizing the IP limited CDN services, you will be required to update your allowed list to include the new range (in bold below) before the change. You will be notified once the change has been completed and the old IP addresses can be removed. For the Federal environment IPs, please reach out to Workspace ONE Support team.

Frequently Asked Questions (FAQs)

How do I benefit from the IP limited CDN solution?
If you have a Dedicated SaaS environments (also known as Managed Hosting SaaS), you can opt into IP Limited CDN. By default, Dedicated SaaS environments use open CDN. If you had to disable CDN due to network requirements, please contact your account representatives.

If you have a tenant in a Shared SaaS environment, open CDN will be replaced by IP Limited CDN as the default mode of CDN:

Non-US environments: November 4th, 2021

US environments: November 5th, 2021

Is the IP Limited CDN feature supported everywhere?
Currently, VMware supports this solution only for customers hosted in VMware US (Commercial), Germany, UK and Japan data centers.  We are working on expanding the service to all countries and information will be announced in the near future.

Is the IP Limited CDN solution free?
CDN integration, open or IP Limited, is included as part of the Workspace ONE UEM platform and is enabled by default in SaaS environments.

How is the IP Limited CDN feature different from the default CDN?
The primary difference is that in house applications are delivered only through the specified set of IP addresses included later in this article. The IP limited CDN could be slightly slower compared to the default CDN.

Can I leverage both the default CDN and the IP Limited CDN solutions simultaneously in my SaaS environment?
Workspace ONE UEM only supports one CDN configuration for an environment at a time.

If I am currently using the CDN URL on my allowed list, would IP changes matter to me?
If you are currently using the CDN URL on your allowed list you will not be affected by IP changes. The CDN hostname will remain the same unless informed separately.

Why IP ranges no longer listed for my country?
IP Limited CDN does not require the need for country specific IP addresses. The list of Anycast IPs is just the entry point into the Akamai Content Delivery Network and is not a 1-to-1 mapping to any edge servers. For more information, please refer to the Akamai’s EIB article. Your applications will be delivered by the shortest/best route available to ensure user experiences.
