Who knows what websites and pages are even on the web? There's no index to the web that I know of apart from Google and DuckDuckGo and maybe this Kagi thing. I want to explore the web - surely search isn't the only way to use the web? I imagine it could be fun to explore the web, lists and graphs of interest where I can hop from here to there via list of links or graphs or nodes or something? Does anyone know of anyt…
There have been some websites in the past that allowed one to browse www content by IP address, covering what seemed to be the full range of IPv4 address space. For example, a page with a list of IP address ranges where each address range is a hyperlink. One could then drill down by following hyperlinks to a specific IP address and view whatever was hosted at that address (default host in the case of virtual hosting)…
You probably answered your own question here--I imagine at this point the amount of things on the internet that aren't using some sort of virtual hosting are quite tiny.
Even ignoring everything else, with the IP address exhaustion and the push for SSL (can't get a certificate for an IP address), websites available directly at an IP address just aren't really a thing anymore.
