Currently I’m with lemmy.world, but if i wanted to create my own, to run at my house, would I need to register a domain? I like the idea of having my own domain but also don’t know how the storage works… like if I post to my own, sure it gets stored, but if I post to somewhere on lemmy.world, where does it get stored?
If you have problems finding ddns servers, you can use duckdns or if you have an Asus router, you can register for their ddns solution.
Good luck!
