Let’s Encrypt Begins Supporting IP Address Certificates (linuxiac.com)

Who benefits from this? Even though Let’s Encrypt stresses that most site operators will do fine sticking with ordinary domain certificates, there are still scenarios where a numeric identifier is the only practical choice:

Infrastructure services such as DNS-over-HTTPS (DoH) – where clients may pin a literal IP address for performance or censorship-evasion reasons.
IoT and home-lab devices – think network-attached storage boxes, for example, living behind static WAN addresses.
Ephemeral cloud workloads – short-lived back-end servers that spin up with public IPs faster than DNS records can propagate.

Would this work with a public dynamic DNS?

[–] SteveTech@programming.dev 12 points 11 months ago

With dynamic DNS? Yeah it always has, as long as you can host a http server.

With a dynamic IP? It should do, the certs are only valid for 6 days for that reason.
