Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Do you need a domain name if you are hosting a Lemmy instance, or will it work fine with just an ip-address + port (e.g. <username>@<ip-address>:<port>)?

yes, there had to be catch, although the guy in this letsencrypt support thread is a senior Letsencrypt engineer and he seems to be saying it is possible - although letsencrypt doesn't support it. I do think you'd have to show a bit more to the issuer to prove ownership than an http acme challenge though.

It doesn't make a lot of sense for LetsEncrypt to spend time adding support for such certs, since both a domain name and a cert from another CA are cheaper than buying an IPv4 block
