Spoofing your MAC address to gain unauthorized access to a network is beyond the scope of this article. If you change your MAC address and you connect to a public network your actual MAC address will never be stored.Ī couple of bad reasons would be to extend your length of time on a specific public wireless network or to “spoof” a MAC address and gain access to a wireless or wired network that is using MAC address filtering.
