How to Generate UUIDs:

A Universally Unique Identifier (UUID) is a 128-bit number used to uniquely tag digital information without needing a central registry. While traditionally displayed in human-readable 8-4-4-4-12 hex format (like ba6eb330-4f7f-11eb-a2fb-67c34e9ac07c), how those 128 bits are constructed varies wildly across the 8 different standardized versions defined by the Internet Engineering Task Force (IETF). You can always identify the version of a given UUID by checking the 13th character in its string representation. Comprehensive Breakdown of UUID Versions
