Frequently asked questions
What are the different UUID versions?
Common versions include version 1 (timestamp-based), version 4 (random), and version 5 (name-based using hashing), each generated using a different method.
Why would a UUID fail validation?
A UUID must follow a specific format of hexadecimal characters and hyphens in fixed positions, so a typo, wrong length, or missing hyphen will cause it to fail validation.
