Unknown device with Null IP Address

I've just installed my BT Smart Hub 2 and have one device listed as unknown and with a Null IP address. The attached photo shows the details. Anyone know what it might be?

Switch off (or put into aeroplane mode) any iOS14 devices you may have then enter http://192.168.1.254/my_network.htm into a browser and click on the Remove button alongside the device, does it come straight back up when you reconnect the iOS device?

Thanks for that Les. I did what you suggested and both my iPad and iPhone were both added to list when I restarted them.

As I thought, it's nothing to be concerned about.
