The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.
IPv6 uses a 64-bit Modified Extended Unique Identifier (Modified EUI-64) in the lower half of some IPv6 addresses. A Modified EUI-64 is an EUI-64 with the U/L bit inverted. [6] There are other identifiers that may be formed using the OUI but those listed above are the most commonly used.

A 64-bit interface identifier can be derived from the interface's 48-bit MAC address, although stable privacy addresses are now recommended as a default instead. [2] A MAC address 00-0C-29-0C-47-D5 is turned into a 64-bit EUI-64 by inserting FF-FE in the middle: 00-0C-29-FF-FE-0C-47-D5. [f]
Virtual machines receive a MAC address in a range that is configurable in the hypervisor. [15] Additionally some operating systems permit the end user to customise the MAC address, notably OpenWRT. [16] Usage of the node's network card MAC address for the node ID means that a version-1 UUID can be tracked back to the computer that created it.
The Portal was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz. [1] [11]It was equipped with 64 kB of main RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (in separate blocks), a LED 32-character one-line screen, a floppy disk (capacity - 140 000 characters), a thermal printer (speed - 28 characters/second), an asynchronous channel, a synchronous channel, and a 220-volt ...

An Ethernet packet starts with a seven-octet (56-bit) preamble and one-octet (8-bit) start frame delimiter (SFD). [d] The preamble bit values alternate 1 and 0, allowing receivers to synchronize their clock at the bit-level with the transmitter. The preamble is followed by the SFD which ends with a 1 instead of 0, to break the bit pattern of ...
