Question

The network in abc company is using the network address 192.168.1.64 with mask 255.255.255.192. In the network the servers are in the addresses 192.168.1.122, 192.168.1.123 and 192.168.1.124. An attacker is trying to find those servers but he cannot see them in his scanning. The command he is using is: nmap 192.168.1.64/28 why he cannot see the servers?

Answer 1

He needs to change the address to 192.168.1.0 with the same mask.

Answer 2

The user is unable to see the server as the servers are not in the desired range.

• A network address is a physical or a logical address that uniquely identifies a computer or a telecommunications network node or system.
• In the current system, the user is scanning from address 192.168.1.64 to 192.168.1.78 because of /28 mask, but the servers are not in that range.
• Thus, the user needs to change either the mas, the address or the server.
