Hi -- glad you like the post. /32s are individual DNS resolver IPs we observed in each country from among the sample we took (half a percent of the traffic we saw during a 24h period).
The >10Q column is how many of those resolvers we saw that did >10Q from among our sample -- you can see there are many fewer resolvers that are doing even moderate amounts of traffic.
