Tl;dr: you can add millions of sites to a single IP if you want. Very common in commercial hosting as well.
I would advise against running millions of domains on a single IP, you will run into issues with a lack of ports that are not in use for the reverse proxy/backend connections unless you are dealing with websites that are basically never used.
I mean... if you're running millions of sites on one box, and that itself isn't an issue, I'd assume your port saturation/traffic is pretty low.
Sure.. this was just said to simplify what is technically possible. Should you? No maybe not, for multiple reasons. Can you, technically? Yes absolutely. I don't know what's the limit but I know that if you have to ask here on lemmy, you might not be anywhere near that limit. Unless you are the go daddy.
