To the best of my knowledge, the IP blocks in the 8.0.0.0/8 range announced by cloudflare are their VPN exit blocks.

I had similar issues with them in the past spewing weird traffic. Didn't really ever reach a conclusion on it, other than just reducing logging for that error condition a scanner was triggering.

How did you discover this? Anyway thanks for additional information

Enabling Warp via the "1.1.1.1" Android app gets me an 8.x.x.x VPN address, at least. This /24 appears to be routed to my city's Cloudflare node, so presumably there's a /24 per city they run this service in.

Running a quick port scan from my phone against one of my machines works, so it doesn't look like they are restricting this too heavily.

And I'm not logged into this app and haven't granted it additional permissions, so I'm not sure they have any idea who I am here.

via support ticket with cloudflare. They didn't explicitly confirm it, but my experience is that they would have corrected me if that was wrong :)

jimsi, employees are also extremely active on Twitter. It’s not the most scalable but that’s usually my goto for eyebrow raising Cf related questions.
