Private IP addresses are reused across multiple networks, thus preserving valuable IPv4 address space and extending addressability beyond the simple limit of IPv4 addressing (4,294,967,296 or 2^32). In the IPv6 addressing scheme, every possible device has its own unique identifier assigned by the...
Purpose: There are some IP address ranges available publicly where one could determine the approximate number of hosts that exist on someone’s network by scanning them. Method: Nmap and similar tools help to scan networks to discover devices within them. Importance: Understanding the network’s ...
