MAC Filter or MAC Limiting: MAC filtering, also known as MAC address filtering or MAC limiting, is a network access control technique where a network device, typically a router or switch, uses a list of allowed MAC addresses to determine which devices can connect to the network. Unauthorized devices with MAC addresses not on the list are blocked. This method can improve network security but should be combined with other security practices, as MAC addresses can be spoofed by knowledgeable attackers.
