Macrelated
MACrelated typically refers to topics associated with Media Access Control (MAC) addresses, which are unique identifiers assigned to network interfaces for communications at the data link layer of computer networks. MAC addresses enable devices on the same local network segment to identify one another and manage access to the shared medium.
A MAC address is usually 48 bits in length, displayed as six hexadecimal octets (for example, 00:1A:2B:3C:4D:5E).
In operation, MAC addresses function within local networks. Ethernet frames carry destination and source MAC addresses,
Security and privacy considerations include MAC spoofing, where a device adopts another’s MAC address to bypass
Note: MAC can also refer to Message Authentication Code in cryptography, a different concept outside the networking
