[NANOG] Re: ISPs in Spain are blocking CDN IP ranges to tackle soccer piracy

[Mark Andrews via NANOG <nanog () lists nanog org>]

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.
