About UUID Versions
Version 1: Time-based UUID using timestamp and MAC address (or random node).
Version 3: Name-based UUID using MD5 hashing. Requires a namespace UUID and a name.
Version 4: Randomly generated UUID. Most commonly used for general purposes.
Version 5: Name-based UUID using SHA-1 hashing. Similar to v3 but more secure.
Format: xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx
Where M is the version (1-5) and N indicates the variant.
