[they] pinged 3.7 million IP address blocks—representing almost a billion unique IP addresses—every 11 minutes for two months earlier this year. They asked the simple question: When are these addresses active and when are they sleeping?
The team found some interesting trends. IP addresses using home WiFi routers in countries like the US and Western Europe were consistently on (or awake) around the clock, whereas addresses in Eastern Europe, South America, and Asia tended to cycle more regularly with day and night.
Why is this important? Think of it as a method for differentiating between a “sleeping” internet and a “broken” internet.
