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
