A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across time and space. It's commonly used in software development for unique keys.
UUID v1 includes timestamp and MAC address information, while UUID v4 is completely random. v4 is more commonly used for privacy reasons.
Yes! UUIDs are designed to be globally unique. The probability of generating duplicate UUIDs is astronomically small.
Absolutely! These UUIDs are generated using standard algorithms and are suitable for production use in databases, APIs, and applications.
