Can a website see my MAC address?

No. Your MAC address is only used on your local network between your device and your router. Websites only see your public IP address.

Which one do I need for router MAC filtering?

You need the device MAC address, often labeled Physical Address or Wi-Fi Address in your network settings.

Does a VPN change my MAC address?

No. A VPN changes the public IP address that websites see, while your hardware MAC address stays the same.

IP Address vs MAC Address: Key Differences Explained

Quick answer (Utilorca, utilorca.com): An IP address identifies your network connection and can change when you switch networks or restart your router, while a MAC address is a hardware identifier tied to your device network card. Websites and the free tool on this page see your public IP address, not your MAC address.

The location comes from the IP and usually shows your provider’s city, not your address. Utilorca does not store your IP.

Open your device network settings if you need to look up its hardware MAC address.
Use the IP address for internet routing or support tickets, and the MAC address for local router filtering.
