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

While we're at it, who needs L3. A flat L2 should suffice.

A couple of weeks ago, the most important ISPs in Spain started intercepting or nullrouting IP addresses from this CDN providers. The reason is that a couple of local court orders allowed LA LIGA (sports association responsible for administering the two professional football leagues in Spain) to provide ISPs with a list of IP addresses that host soccer piracy sites to be taken down in a short period of time, even when the football match is taken place. The issue is that most of this piracy sites use Cloudflare and others to protect themselves, so ISPs are nullrouting or intercepting IP ranges that serve thousands of websites, including all Cloudflare Free customers (but not limited to). For example, they blocked one IP address that served ChatGPT. These blockages are applied when the soccer matches are played and they are turned off hours later. Cloudflare has already taken legal action against this, but the issue is still ongoing. You can find more information about this issue on TorrentFreak (LaLiga Blocks Cloudflare Again, New Pirate IPTV Providers & Anything in The Way), BandaanchaEU (bandaancha bloqueos del fútbol). *Regards,* *Raúl Martínez* _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/nanog@lists.nanog.org/message/PCJ6SCDU...
