Architecture of Universally Unique Identifiers (UUID)

A UUID (Universally Unique Identifier)โ€”also known as a GUID (Globally Unique Identifier) in the Microsoft ecosystemโ€”is a 128-bit identifier standardized by RFC 4122.

Version 4 (Random) Anatomy

A standard formatted UUID consists of 32 hexadecimal digits displayed in five groups separated by hyphens:

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx Where `4` indicates Version 4, and `y` is one of `8`, `9`, `a`, or `b` indicating the RFC 4122 variant.
