Since the middle of August the crawler has been recording the time when hubs join and leave the network. This allows for certain time based trends to be realized. The hub is identified by its IP address. One way to visualize a set of IP addresses is with the Hilbert curve which was made popular by xkcd. The tool I used is called ipv4-heatmap. By generating a heatmap every 2 hours and then playing the images in order a time lapse video is produced. This video will show when users in different parts of the world are online depending on the time of day and the day of the week.
Here is a rough breakdown of what the video shows:
- On the right side half way up is where a lot of Brazilian users are.
- Above them is where a lot of Asian IPs are.
- In the bottom left is where Europe is.
- In the center left and the top center is North America.
Consult the ipv4-heatmap website for more details on IP distribution or the slightly outdated internet map from xkcd.
Thanks to Daisuke from irc.p2pchat.net #shareaza for his excellent work converting the images to a video.
