129.100.0.79/24 would specify all hosts that vary in the lower 24 bits.An IP range in this notation has the form how many of the top bits of the IP address are fixed. We can use the CIDR notation to specify a network range.
The University of Western Ontario, however, administers many hosts… an entire network in fact. Typically an IP address is written as four base-10 octets example, the IP address of uwo.ca is 129.100.0.79.
Recall an IPv4 address is specified by 4 bytes (32 bits), constituting an integer value between 0 and 2^32-1. Network Exploitation - nmap and Metasploit Network Reconįinding a target device to attack depends on the hacker’s objectives and may be opportunistic or targeted.Įither way, the first step in remote exploitation is to discover the target and gather After all, one cannot exploit a host that does not exist! The next step consists of gathering public information about the target, including what ports are open and which applications are available over the network.
