Unique Identification Marking, UID marking, Item Unique Identification or IUID, is a part of the compliance process mandated by the United States Department of Defense. It is a permanent marking method used to give equipment a unique ID.
As in other UUIDs, 4 bits are used to indicate version 4, and 2 or 3 bits to indicate the variant (10 2 or 110 2 for variants 1 and 2 respectively). Thus, for variant 1 (that is, most UUIDs) a random version 4 UUID will have 6 predetermined variant and version bits, leaving 122 bits for the randomly generated part, for a total of 2 122 , or 5.3 ...
