About UUIDs
Version 1: Time-based UUIDs that include timestamp and MAC address information. These are sequential and can reveal information about when and where they were generated.
Version 4: Random UUIDs that are generated using random or pseudo-random numbers. These are the most commonly used type and provide good uniqueness without revealing system information.
UUIDs are 128-bit values typically displayed as 32 hexadecimal digits in groups of 8-4-4-4-12 format.
