Sorry I misunderstood the fact that you were talking about sending IPs and not randomly generated dns name from cloudflare. My question was does this app use use a custom protocal, and I'd define a pseudo random IP provider over push notifications to be a cudtom prptovol.

This is a nation state suppressing information, I don't see why wholesale blocking services like cloudflare or any of the other possible options would be a non-starter, given it only needs to last for a weekend. There also doesn't appear to be any evidence that this app uses any of these techniques either as far as ive sedn.
