1.1.1.1 was never a valid address. It’s always been labelled as a research prefix and never publicly routed —

It will break stuff that was broken anyway. Anyone who decides to use a valid IP address that’s not RFC1918 for their own internal use deserves what’s coming to them. RFC1918 was specifically to set aside IP address space that is guaranteed not to be globally routable. If 17,891,328 IP addresses set aside for your own personal use isn’t good enough, you’ve engineered a bad network :)

That is gonna break a lot of stuff because 1.1.1.1 is used a lot as a blackhole address on border routers And also as a dns blackhole ip for unwanted dns domains.. Lots of networks will need remodelling to allow access to this service

Cloudflare has announced a new internet-wide DNS resolution service. There's a good writeup on it at

This bit of news isn't much advantage to people on the tunneled AMPRNet, but the writeup is nonetheless interesting. - Brian
