Apparently, kinda gross looking? Maybe I should find a different map.
The above map was generated using IP address information (well actually, it's a bit more complicated than that), but other maps exist. There's one that monitors online activity much like a heat map. Here's another that uses traffic rankings and statistics to lay out a map of websites.
You'll notice that there are hills and valleys that naturally arise within the maps that are based off online content. You've got your brightly lit areas, which represent places of high traffic. You can also find smaller, less-ventured corners of the Internet among these larger hubs.
But even these maps don't cover everything there is to see about the Internet. There are parts of the Internet that are impossible to map by conventional means. There are even parts of the Internet that arguably might not really be part of the proper "Internet" at all. Today, we're going to take a look at these hidden areas of the network.
