 This happens because your Beagle is running a DHCP server that will provide your computer with an IP address of either 192.168.7.1 or 192.168.6.1, depending on the type of USB network adapter supported by your computer's operating system. Your Beagle will reserve 192.168.7.2 (in Windows) or 192.168.6.2 (in MacOS/Linux) for itself.
