> The Cloudflare-APNIC experiment uses two IPv4 address ranges, 1.1.1/24 and 1.0.0/24, which have been reserved for research use. Cloudflare's new DNS uses two addresses within those ranges, 1.1.1.1 and 1.0.0.1.
They had acknowledged to themselves going into it that the IPs weren't "normal". They could have easily chosen a safer range if that was a priority.
1.1.1.1 is a normal IP as it was reserved for internet use. There are already IP ranges that are supposed to be used for internal use, and 1.1.1.1 is not one of them
1.1.1.1 is widely known to be a dumping ground of random traffic, as well as a common internal address for captive portals and whatnot. The entire rollout of 1.1.1.1 has been characterized by legacy bugs and misconfigurations of network hardware preventing its proper use. Regardless of what the standards say about 1.1.1.1, it was a poor choice if Cloudflare values widespread adoption.
