Is the operating system the one responsible for giving you a mac address or is that in the cable modem? If you change your cable modem, does your mac address change?

It is stored in the Network Interface Device (NIC), basically the device that give you access to the internet, whether it be the wireless card or the ethernet controller.

It will not change if you change your modem.

Each hardware device has it's own unique MAC address. Normally the MAC for a cable modem will be printed and adhered on the bottom or rear of the device. If it's a PC component it will be labeled on the device in a similar fashion.

In windows, open a command prompt and type ipconfig /all. The physical address is the MAC address. As neieus said, each hardware device will have it's own MAC address.

Can you change the mac address? Is there a chance of messing it up? There's tutorials on the web on how to do it, but is it safe to do? The tutorials say to make up a random sequence of numbers and letters

There are ways to spoof a MAC address, but the reasons for changing them are usually dubious. The first three octets identify the manufacturer. Also, the MAC address is embedded in the device so you aren't actually changing the device's MAC address, but rather hiding it from the OS and network.

Changing a MAC address isn't physically harmful, but your network may respond differently to the device. (i.e. DHCP address assigned via MAC)

I like to compare them to a fingerprint. Each device has one and no two are the same.

Just like a fingerprint it can't be change, but just like a fingerprint, it can be altered somewhat.

Many routers offer the option to change he MAC address the modem sees. That is there because some modems get linked to a MAC address from your networ card and when a router is connected they no longer work. That option enables you to change the MAC address that the modem sees from the router to match the PC so the modem sees is properly.
