For anyone looking at https://arxiv.org/pdf/2002.07747.pdf to get an estimate on the actual # of IPFS nodes, note that these tools are trying to crawl the number of nodes acting as "DHT Servers" in the Public IPFS DHT. Nodes behind home firewalls or NATs don't become DHT routers because they aren't dialable, and other large users intentionally set many of their nodes into a lower-bandwidth client mode. Also, many applications run their own private IPFS networks (like OpenBazaar for instance) and don't participate in the Public IPFS DHT, so wouldn't be reached through a crawler here.
