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.

A single question mark is sufficient. – Spiff Mar 29 '10 at 14:53
Given the first revision, I'm not sure if now showing shouldn't read not showing instead? – Arjan Mar 29 '10 at 15:50
@sahil, please "associate" your accounts at, after which you'll be the owner of the above question again. Next, please edit the question to make clear if ipconfig does, or does NOT, show any MAC address. (And just like I commented on Server Fault, see also – Arjan Mar 29 '10 at 16:09

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...
