Hi, thanks for choosing Dell. We cannot identify the MAC address whether it is wired or wireless device based on MAC address since it is a just Hardware address only for a network device and no such feature in OUI as well.
From a network perspective, if you see a device in the arp table on a router, can you tell if it's wireless based on the mac address? Does Dell use different OUIs on wireless network adapters than wired?
Can you tell if a Dell device is wireless or wired by the OUI in the mac?
