(ETA: What if you can't get to the Console port? How do you get the IP address of the switch in order to SSH or (if you must) Telnet in?)Ĭouldn't you just use CDP? #show cdp nei detail will show you the ip of the connected devices. The amazing thing to me is, this far into the 21st Century, this is still the only way I could find to get this information - i.e. Also, 'sh ip arp | i 0/24' will show just the MAC address(es) on that port.)

What are your overall thoughts on this new privacy feature? Do you adjust or toggle Wi-Fi Private Address for particular networks? If the general topic of privacy interests you, donât miss out on our other articles on the subject matter.

Resetting the network settings on your device will also change the private Wi-Fi address it uses for the connection, along with any customizations to network settings.Īlthough Private Addresses can reduce user tracking and profiling, you could face connectivity-related issues on some Wi-Fi networks. This is why youâre prompted to reconnect to the Wi-Fi network. Itâs worth pointing out that each time you disable and re-enable Private Address, a new Wi-Fi address will be used with the network. Thatâs pretty much all there is to it, now you know how easy it is to use (or not use) Private Wi-Fi addresses on your iOS or iPadOS device.

However, devices running iOS 14 and iPadOS 14 and newer use a different MAC address for each network, thereby helping to safeguard your privacy. Normally, when you connect to multiple networks, the same MAC address is used, which makes it easy for network operators and observers to track your activity and access your location over time. When you connect to any Wi-Fi network using any device, the device needs to identify itself to the network using a MAC address.
