What is?

Hi, I am trying to check what is connected to my internet.
e.g. what is 16:EA:11:2E:5B:BC ?

That MAC address is for a Wifi or Bluetooth chip from Espressif Systems, but their chips are used in lots of different devices so it does not really narrow it down. You could always block it and see what stops working.

When this was done in a work environment it was called "scream testing".

Thanks, I am using My devices.
It currently shows 4 Wi-Fi 3 Wired & 2 Offline
3 Wi-Fi are identified with MAC address. I am guessing one will be my iPhone
I am thinking rather than blocking, if I switch off devices 1 by 1, I should see it as offline.
There a function in My devices where I can name each device for future reference.

TV, Alexa or Google home automation?   Fridge, washing machine etc?   I thought what have we come to when the washing
machine wants internet access.

Yes, it is mad. Perhaps I am being overly concerned about unidentified devices?

I think it's perfectly reasonable to want to know what devices are connected to your network. As unlikely as it is, anything unknown could potentially be malicious.

I would echo the approach above of disabling it and seeing if anything you care about stops working.

The good old "Switch it off and see who complains" - we do that in the data world too.

Excuse my senior moment, but how do I switch off an unknown device?

There'll be a toggle to disable the MAC address in your router pages (My Devices you mentioned before?). I assume you're seeing 16:EA:11:2E:5B:BC in your router?

If you post your router model number we'll be able to find the manual (it will probably be on Google) and advise.

Not in the Vodafone My Devices app. I could log in and check out the router.

Maybe I should just forget about it?
Possibly something silly like my washing machine / dishwasher
