UUID Versions Explained

Version 4 (Random)

UUID v4 is the most commonly used version. It is generated using random or pseudo-random numbers. There are approximately 5.3 x 10^36 possible v4 UUIDs, making collisions practically impossible for any realistic application.

Version 1 (Time-based)

UUID v1 is generated from a time and a node ID (usually the MAC address). This version has a temporal component, meaning IDs are roughly sortable by the time they were created.
