- In terms of history, humans can presume that MAC addresses were discovered by Xerox PARC researchers.
- In the place of MAC address, numerous similar notions are employed, such as physical address, hardware address, and ethernet hardware address of a network device.
- Even BIA (burned-in address, notably for Cisco Router Switches) is frequently used to refer to the same thing.
- The network interface card (NIC) is a computer circuit card that allows users to connect to a network on their computer. It converts the data into an electrical signal that may be delivered via the internet.
- In a system, there is a hardware address as well as an IP address.
- TCP / IP addresses are linked to IP addresses, whereas network adapter hardware is linked to MAC addresses.
- The first six digits of the MAC address are used to provide manufacturer info; this is known as OUI (Organizational Unique Identifier).
- The last six digits of a Network Interface control system are assigned by the manufacturing firm.
- A network manager discovers consistency in identifying information sent and received on the network using the MAC address.
- The only reason for this is because, unlike dynamic IP addresses, MAC addresses do not change over time.
- Because the first three bytes (OUI) of a MAC address are reserved for the producer, the same producer is limited to just 2 24 unique addresses per OUI.
- We may say that MAC address sorting is simple to fake. Because Ethernet is broadcast, one can operate in disguise and only listen to and from recognised MAC addresses.
- In most cases, an attacker can get network access by repeatedly changing his MAC address to one that is acceptable.
