I accidentally found that Let's Encrypt certificates for IP address are generally available: https://letsencrypt.org/2026/01/15/6day-and-ip-general-availability
Have anyone tried to use them?
I remember about these ideas to avoid centralized DNS and use kind of phonebook instead, like:
1.2.3.4 latest news
199.100.100.211 tasty meals
12.13.14.15 Jane blog
Such idea described @aral in this https://ar.al/2025/06/25/web-numbers/ (Web Numbers) article and now seems to be more doable.
