My USB modem is now showing its MAC address in ipconfig /all.
So does that mean that a USB modem has its own MAC address?

This question came from our site for system and network administrators.
Your dial up analogue USB modem probably does not have a MAC address - it doesn't do Ethernet, it connected to your PC using a Com port, hence it has no need for a MAC address.
Your ADSL USB modem may have a MAC address as it may connect to your PC using a virtual Ethernet interface, hence it needs a MAC address.
Lets face it - if ipconfig /all shows a MAC address it's safe to say it has one...
