In a blog post on the ICANN website, Joe Abley writes: "Resolvers are servers on the Internet which use the Domain Name System (DNS) protocol to retrieve information from authoritative servers and return answers to end-user applications… So, all in all, how many resolvers are there? Given that anybody can run one, it seems like a difficult thing to measure. It turns out, however, that all resolvers that talk directly to authoritative servers on the Internet leave a trail, and with a little data crunching we can come up with a number."
