A MAC address (short for medium access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection ...
Lipogram. A lipogram (from Ancient Greek: λειπογράμματος, leipográmmatos, "leaving out a letter" [citation needed]) is a kind of constrained writing or word game consisting of writing paragraphs or longer works in which a particular letter or group of letters is avoided. [1][2] Extended Ancient Greek texts avoiding the letter ...
One (SPBM) is intended where complete isolation of many separate instances of client LANs and their associated device MAC addresses is desired, and it therefore uses a full encapsulation (MAC-in-MAC a.k.a. IEEE 802.1ah). The other (SPBV) is intended where such isolation of client device MAC addresses is not necessary, and it reuses only the ...
On Aug. 7, 2024, Cybernews researchers discovered that MC2 Data, a background check firm, had left an unprotected database containing 2.2TB of personal data accessible online without password ...
It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [ 1 ] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload.

MAC flooding. In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches. The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where ...
MAC address anonymization performs a one-way function on a MAC address so that the result may be used in tracking systems for reporting and the general public, while making it nearly impossible to obtain the original MAC address from the result. The idea is that this process allows companies like Google, [1] Apple [2] and CrowdVision [3 ...
