Appendix E: Finding the MAC Address and IP Address for 
Your Ethernet Adapter
This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC 
filtering and/or MAC address cloning feature of the Router. You can also find the IP address of your computer’s 
Ethernet adapter. This IP address is used for the Router’s filtering, forwarding, and/or DMZ features. Follow the 
steps in this appendix to find the adapter’s MAC or IP address in Windows 98, Me, 2000, or XP.
