X is back, and this is a strategy of changes in the company's IP structure, which stopped using its own IPs and now uses IPs from the Cloudflare block. This change frees up X due to the change of IPs that were blocked in Brazil. In technical terms, Twitter used its own IP 104.244.40.0/21 and now uses Cloudflare's range 162.158.0.0/15. What does this mean? If the block is blocked, several other companies will be impacted, and at the moment, it is not possible to block X.

Ah, but X only uses 1 IP... 

Cloudflare uses advanced security strategies to deliver content, and as a result, IPs are sometimes dynamic to meet the large demand for requests managed by Cloudfare's immense infrastructure.

Therefore, operators, if they want to follow the blocking protocol in Brazil, will possibly face some technical difficulties.
