When setting up a small office/home office (SOHO) network, an administrator assigns an IP address to one of the desktop computers manually. The IP address has to enable the computer to communicate within the local network and externally. Which of the following IP addresses would be BEST for the administrator to assign to the device?
Private addresses are used within local networks and cannot be routed through the internet. Choosing an address within the private address space, such as 192.168.0.10, is most suitable for internal network communication, while still allowing the device to communicate externally through NAT (Network Address Translation). The address of 169.254.0.10 is an Automatic Private IP Addressing (APIPA) IP, which is self-assigned by the client computer when DHCP is not available and not suitable for customary network configurations. The address of 172.32.0.10 falls outside the range for private networks and would be considered a public IP. 127.0.0.1 is the loopback address and is utilized for local host testing; it will not allow the device to communicate with other network devices.
