An IP address that starts with 169.254 suggests there may be a problem with DHCP. This is because 169.254 is the prefix for a link-local address, which is an address that is automatically assigned by the device when it cannot obtain an IP address from a DHCP server. A link-local address allows the device to communicate with other devices on the same local network, but not with devices on other networks. A link-local address indicates that either the DHCP server is not available, not configured properly, or not reachable by the device.
To resolve this issue, the device should try to renew its IP address from the DHCP server, or the DHCP server should be checked for any errors or misconfigurations. The other IP addresses are valid addresses that can be assigned by a DHCP server, and do not indicate any problem with DHCP.

According to the Apple Device Support Reference Materials, you can control who can discover your iPhone or iPad when it's within AirDrop range by setting AirDrop to Contacts Only 1 . This means that only people in your Contacts app can see your device and send you content via AirDrop. You can also set AirDrop to Receiving Off, which means that no one can see your device or send you content via AirDrop 1 .

The iPhone Privacy Warning message indicates that the device is using its original MAC address to join the Wi-Fi network, which could allow the network operator or other parties to track the device or profile its online activity. To prevent this, the device can use a different MAC address for each Wi-Fi network, which is called a Private Wi-Fi Address. This feature is enabled by default on devices running iOS 14 or later, but it can be turned off manually or automatically by some networks. To turn on the Private Wi-Fi Address, the user needs to go to Settings > Wi-Fi, tap the info icon next to the network name, and toggle on the Private Wi-Fi Address option. This will generate a new MAC address for the device and rejoin the network. References:
