I wonder how they count the number of nodes. I run a node for about 30 minutes every day. It's main function is to service my wallets, and it seems to work well. Do they sample the network, and count the number of nodes online at that point, or do they run a monitoring system, and register every node that comes on line during that period. Also, I use up to 6 different Internet providers, and some don't provide consistent IP addresses. Will that affect the count?
