Honestly I wonder if even an unusual setup like a static IP would register on one of their heuristics. It could flag as a web server, which would theoretically be more likely to ping a site rapidly than a personal computer.
> Honestly I wonder if even an unusual setup like a static IP
I have internet at home through Comcast, a huge and universally hated ISP in the USA. I also run a home server (though it only takes incoming connections, and does not visit websites itself). I purchased a dynamic DNS service that would update my domain's DNS whenever my home internet's public IP changed.
In over 5 years and through numerous modem reboots, my IP address has not changed once. A year ago I transferred my domain to another provider; I did not bother setting up dynamic DNS again and my website still works fine.
I have not purchased a static IP from Comcast. When I initially set up the server I had read that my home's IP address can change anytime the modem reboots, or possibly anytime at all, to any IP in Comcast's pool - which is why I subscribed to dynamic DNS.
So a static IP may not be as unusual of a setup as you say it is.
Why would a static IP be considered something unusual? I’ve almost always had one with all of the home broadband services that I’ve used over the years.
(Edit: I mean that the static IP was almost always included by default in the standard setup, I didn’t have to request or purchase one)
