Depending on the netmask used, it could be a valid host IP. i.e., The network ID of 192.168.1.0/22 includes 4 'C Blocks' with the following hosts ... 192.168.0.1 -to- 192.168.0.255 192.168.1.0 -to- 192.168.1.255 192.168.2.0 -to- 192.168.2.255 192.168.3.0 -to- 192.168.3.255 -- -- -- \ / \/ /\ / \ -- -- Quoting hannibal blog <hannibalsec () gmail com>: hello list I'm actually doing a blackbox audit of a network, and I'm trying to discover network architecture. I got this output with nmap X.X.X.0/24 interresting ports on X.X.X.0 68/tcp 723/tcp 6000/tcp I'm not sure the network is a C class one, but I'm surprised that such an ip adress is an host IP. What do u think ? Any idea to guess network adressing map ? ------------------------------------------------------------------------------ FREE WHITE PAPER - Wireless LAN Security: What Hackers Know That You Don't Learn the hacker's secrets that compromise wireless LANs.
