In 2022, rightsholders obtained permission in Austria to block several pirate site domains and a list of IP addresses that actually belonged to Cloudflare. ISPs had no choice but to comply with the court's instructions which took out countless Cloudflare customers in Austria. According to reviews conducted by local telecoms regulator TKK, the IP address blocking violated net neutrality regulations and will no longer be allowed.
In other words, only domain blocking will be allowed, IP blocking will not be permitted, and cloudflare IPs must be unblocked again.
