What is Apple's version of Automatic Private IP Addressing?

The correct answer pertains to Apple's implementation of a system that allows devices to automatically assign themselves an IP address when there is no DHCP server available. This automatic configuration process is designed to facilitate communication within local networks without requiring manual configuration by the user.

The term "Bonjour" is Apple's implementation of Zero Configuration Networking (Zeroconf), which incorporates automatic IP addressing along with service discovery. When a device connects to a network and cannot receive an IP address from a DHCP server, it assigns itself an IP address in a specific range (169.254.x.x) and uses Bonjour to discover other devices on the network that may be offering services.

Zero Configuration is a broader concept that encompasses several networking services, including automatic IP addressing, service discovery, and name resolution. Although it refers to the overall process that Bonjour implements, the answer focuses on the brand name that Apple uses for it. Thus, while they are closely related, Bonjour specifically names Apple's version.

The other options provided—AirDrop and iCloud—are for different specific functionalities (file sharing and cloud storage, respectively) and do not pertain to the IP address configuration process.
