About the UUID Decoder
This tool allows you to peek inside a UUID. Different versions of UUIDs encode different types of data:
- v1: Contains a nanosecond-precision timestamp and the MAC address (node) of the generator.
- v6: A reordered version of v1, allowing for better database index locality while preserving the timestamp.
- v7: Contains a millisecond-precision Unix timestamp, making it sortable by time. Best for database primary keys.
- v8: Reserved for custom applications that need a specific format not covered by other versions.
- v4: Purely random bits (except version/variant bits). No metadata to decode.
