Let’s Encrypt begins issuing IP address certificates, expanding support beyond domain names to cater to specialized use cases, such as DoH and home devices.

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.

    I use a domain, but for homelab I eventually switched to my own internal CA.

    Instead of having to do service.domain.tld it’s nice to do service.lan.

        I just use openssl"s built in management. I have scripts that set it up and generate a .lan domain, and instructions for adding it to clients. I could make a repo and writeup if you would like?

        As the other commenter pointed out, .lan is not officially sanctioned for local use, but it is not used publicly and is a common choice. However you could use whatever you want.

          No thanks. I get some people agreed to this, but I’m going to continue to use .lan, like so many others. If they ever register .lan for public use, there will be a lot of people pissed off.

          IMO, the only reason not to assign a top-level domain in the RFC is so that some company can make money on it. The authors were from Cisco and Nominum, a DNS company purchased by Akamai, but that doesnt appear to be the reason why. .home and .homenet were proposed, but this is from the mailing list:

          1. we cannot be sure that using .home is consistent with the existing (ab)use
          2. ICANN is in receipt of about a dozen applications for “.home”, and some of those applicants no doubt have deeper pockets than the IETF does should they decide to litigate

          So, corporate fear.
