If you are seen strange devices on your network
- triple check if these are real devices or not. We have seen users have very old devices attached to their network ...
- It is also possible these are your neighbor's devices ...
- And if (1)(2) are false, then this device is likely a virtual device created by another device. For example
- If you have ATT router 5268AC, you may see another device also named 5268AC. This device is a virtual interface created by the physical device.
How to deal with these devices
- If you know these devices are legit, then please leave them, they are there to provide you some functions.
- If you have no idea what the "parents" of the device is
- Look at the first 3 bytes of the MAC address of the virtual device.
- Match the 3 bytes of the MAC address with other devices...
- We can not recommend how to deal with these devices; but it make sense to use firewalla to block these devices until something is broken.

FYI: I see this ‘unknown’ device show up with Apple devices using the private wifi address setting.
Useful trick for staying private out in the world, but frustrating when on your home LAN when you want to know what every device is!
