MAC Address and VPN

A VPN protects traffic over the internet, but it does not hide your device’s MAC address from the local network you’re connected to. Your MAC address is used at the link layer (Wi-Fi/Ethernet) inside your local network, while the VPN operates at higher layers for internet routing. This matters for privacy: a cafe or hotel network can still recognize a device by MAC unless you use MAC randomization. Most modern phones and laptops support “private address” features that randomize MAC per network, reducing long-term tracking. A VPN complements this by encrypting traffic once it leaves the local network. For travelers, the best practice is to enable MAC randomization (or “Private Wi-Fi Address”) and use a VPN with a kill switch on public Wi-Fi. In enterprise environments, MAC addresses can be used for access control (NAC), so randomization may break login; choose settings accordingly. In DVPN usage, the same principle applies: local network identifiers still exist, so treat VPN as one layer in a broader privacy stack, not a total cloak.
