Appendix
4. Set up MAC Filtering
Each networking device (router, network card, etc) on a network contains a unique hexadecimal
number that identifies that specific product. This number is referred to as a MAC address. MAC
filtering allows you to create a list of the MAC address of each device on your network and only
allows these specific devices to associate with your network. With this feature enabled, devices
attempting to connect to your network with a MAC address that is not in the list you created, will be
denied access.
