Developers (two dudes) are super responsive and would likely release an IP customization feature upon request. Is there any service that would tolerate this [D]DOS-y kind of behavior that would feel more privacy friendly than Cloudflare?
IsThereNet [for macOS] watches for internet connection status changes and draws a colored line at the top of the screen to indicate the status.
Edit: Thanks everybody!
(1) ICMP (Internet Control Message Protocol) Echo Requests hardly constitute a burden on a server.
(2) There is little privacy concern simply exposing your IP to Cloudflare.
(3) Uptime-Kuma can be self hosted to accomplish this task with more bells and whistles.
(4) There is an appetite for daydreaming of DDOSing bad Alphabetic actors ;) You civilly digidisobedient rascals!
If the other traffic is already correlated to your IP, then what additional info does an ICMP echo leak?
It tells when the user is online. This is useful for sending spam, because being on top of the inbox makes it more likely your message will be read.
To be fair, I doubt anyone’s implemented this specifically for ICMP. Instead I’d expect tracking that watches for any IP traffic whatsoever, and that happens to include ICMP.
But this user plans to leave ping running all the time to check that their own Internet connection is working.
Either way, at any given time there's tons of traffic leaving your network, it just means that software is active, not that a human is active. On top of that, Cloudflare probably isn't selling the fact that an ICMP ping was received at their DNS server directly to spammers quickly enough for them to act and put an email at the top of your inbox, assuming that spam isn't caught by a spam filter first.
