Six day and IP address certificate options in 2025

Kinda funny to call the current 90 day certs "long lived". When Let's Encrypted started out more than 10 years ago most certs from major vendors had a 1 year life span. Let's Encrypt was (one of) the first to use drastically shorter life spans, hence all the ACME automation effort.

To someone like me with hobby-level serving needs, the 90 day certificate life is pretty inconvenient, despite having automation set up. I run a tiny VPS that hosts basic household stuff like e-mail and a few tiny web sites for people, and letsencrypt/certbot automation around certificate renewal is the only thing that I seem to need to regularly babysit and log in to manually run/fix. Everything else just hums along, but I know it's been 90 days because I suddenly can't connect to my E-mail or one of the web virtual hosts went down again. And sure enough, I just need to run certbot renew manually or restart lighttpd or whatever.
