"Olafur Gudmundsson 6 Quarters • a day ago
Due to various reasons 1.1.1.1 does not work for fraction of the
internet; We are working in fixing that. The issues involved include;
Network filters; various devices that use 1.1.1.1 internally; etc. Stay
tuned for followup blogs and for now use 1.0.0.1 or our IPv6 addresses..."

"For IPv6, we have chosen 2606:4700:4700::1111 and 2606:4700:4700::1001
for our service. It’s not as easy to get cool IPv6 addresses; however,
we’ve picked an address that only uses digits."
