I remember being surprised when Cloudflare launched https://1.1.1.1 with a valid cert and I immediately wanted one, but couldn’t find an easy way to get one.
I am gonna try to run a DoH resolver on this and see how it goes.

The coolest easiest to remember ip address I ever used was mimsy.cs.umd.edu: 128.8.128.8
For others who don't know how certificate for IP addresses relates to a DNS-over-HTTPS server: https://blog.cloudflare.com/announcing-ddr-support/
I’m really glad they have a page on that IP. I use it decently often for “is the problem DNS?” troubleshooting.
Because if zero pages load, but that one does, the issue is DNS.
Ping is easy too of course, but I can ask people to type four ones with periods between into their search bar over the phone. No command line required.
This was a fun conversation.
I remember calling Clint and Jeremy at DigiCert and asking: "hey we have this cool IP address—what are the odds you guys can issue a certificate for it?"
I'm not sure if they had to dust off some code or process to do it, but they got it done really quickly once the demonstration of control was handled.
