   The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing.

3. MAC-Forced Forwarding - Wikipedia

   en.wikipedia.org/wiki/MAC-Forced_Forwarding

   When a host tries to access the network through a switch port, DHCP snooping checks the host’s IP address against the database to ensure that the host is valid. MACFF then uses DHCP snooping to check whether the host has a gateway Access Router. If it does, MACFF uses a form of Proxy ARP to reply to any ARP requests, giving the router's MAC ...

6. MAC filtering - Wikipedia

   en.wikipedia.org/wiki/MAC_filtering

   In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the ...

7. IP address blocking - Wikipedia

   en.wikipedia.org/wiki/IP_address_blocking

   Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
