Why does your isp need to know the mac address of your cable modem or dsl modem?

The MAC address (Media Access Control) is used to identify a specific piece of network hardware, such as a network interface card (NIC), a router or a modem. Since your ISP will only wish to allow internet access to paying customers, it can check the MAC address of your router against its list to see if it belongs to a valid customer. If you change your equipment, typically, your ISP will provide you with a process to register the new hardware's MAC address with them.

∙ 6y agoDepending on your ISP (dialup, dls, isdn, cable, FIOS) the ISP may use the MAC address to identify the modem device at your site connecting to the MAC address of the device at the ISP site.
Usually Cable company's use a MAC address (which is unique to ANY network device, there should be NO two MAC address' alike on the same LAN), because they need a router/ modem or computer to register that the connection is really coming from yourhouse/ device and someone hasn't hacked into the cable outside your house to steal the internet connection. This way if two devices with different MAC address's try to access the internet it will shut down the connection if there is a foreign MAC address trying to access the connection also.

Some cable companies restrict the modems it allows their customers to use. Check with your cable provider.
