I have a verizon HTC One M8 running Android 6.0. I recently noticed that the network name that appears on my routers DHCP list for this device is "X2E GmbH". I confirmed that this device is indeed my phone by comparing the MAC address, but I can find no information where this network name came from.
This seems awfully suspicious as the first result for X2E GmbH on google results with a German company which sells datalogging equipment. This is not a rooted phone, so it seems more likely that the network name change may have come from something malicious within my computer network.
Does the network name originate from my phone? What should a default network name be?
