What is the default IP address of the controller when using the startup wizard?

The default IP address of the controller when using the startup wizard is 172.16.0.254. This address is part of the private IP address range defined by the Internet Engineering Task Force (IETF) and is commonly used to provide a default configuration for devices in a private network. When a controller is initialized for the first time or reset to factory settings, this default IP address allows the administrator to easily access the controller's configuration interface.

Using this IP address ensures compatibility and ease of access on a typical local network setup. The choice of a default address in the private address space also helps to minimize conflicts with public IP addresses and maintains a level of network security within isolated environments. The other choices represent different IP addresses that are either within different ranges or serve different purposes, but are not the default configuration for the Aruba controller.
