Traditionally the authorities look towards ISPs to implement censorship orders via DNS blocking. However there are other DNS providers that perhaps via encrypted DNS that work around ISP block.
Now the Italian courts have decided to order DNS provider
Cloudflare to block a couple of pirate internet TV services. Last year, Sky Italy and the top tier Italian soccer league Serie A took Cloudflare to court, hoping the company would block access to two IPTV services, ENERGY IPTV and IPTV THE BEST.
Cloudflare lost both cases. Cloudflare then appealed the injunctions, arguing that it only acts as an intermediary for web content.
The court was not convinced by the arguments. In the ruling, the court said that by facilitating the sites'
availability, Cloudflare indeed is involved in copyright infringements. The court also said that the blocking should be dynamic, meaning if the sites change IP addresses, Cloudflare should still block them.
