Theoretically IPv6 should provide enough addresses that a CDN doesn’t need to share an address between customers . Give each machine a /64 or longer and assign the customer a unique addresses within that prefix. Use the ability of modern kernels to bind to a range of addresses/interface and check the name to address mapping before returning content in addition to checking that it is configured for the name. You can share resources without sharing addresses. -- Mark Andrews
