Every device on an Ethernet network has an Ethernet address. The manufacturer permanently programs this address into the network interface card. The Ethernet address is NOT the same as the IP address. These two Ethernet examples show the same address. Some systems report the Ethernet address using hyphens between pairs of characters and others use spaces.
Some systems use upper case letters and others use lower case.
For entry into this form, use spaces between pairs of characters and lower case letters , as the second example shows. The Ethernet Address will be displayed as the Adapter Address. Enter the Adapter Address from YOUR PC into the registration form. This address is for your PPP Adapter, which is used for dial-up networking on your modem. To see the address of your Ethernet Adapter, click on the down arrow and select your Ethernet Adapter from the list.
