UUID Information
UUID v4 (Random)
Generated using cryptographically strong random numbers. Contains 122 bits of randomness, making collisions extremely unlikely.
UUID v1 (Time-based)
Contains timestamp and node information. Guarantees uniqueness across time and space but may reveal information about the generating system.
NIL UUID
Special UUID with all bits set to zero. Used to represent the absence of a value or as a placeholder.
