Earlier today while working with a friend at our offices we were playing around with a large NMAP scan of the anoNet network. His computer would not open the network topology in Zenmap because of a lack of RAM so we were looking at it on another laptop with much more RAM. After discussing it for a little bit we were curious how many hosts had been discovered on anoNet but initially I didn’t see an easy way to get this information.
