Online UUID Generator - Version 1

UUID Version 1 generates unique identifiers using the current timestamp, a clock sequence, and the device’s MAC address. The timestamp ensures uniqueness over time, while the MAC address ensures uniqueness across different machines.

Pros:

• Globally Unique: Guaranteed uniqueness even across different devices.
• Roughly Sortable: Useful for indexing since it's timestamp-based.

Cons:

• Privacy Concerns: Embeds the device’s MAC address, potentially exposing network details.
• Predictable: Can be guessed due to its time-based nature.

Best for: Distributed systems where global uniqueness is required, and privacy is not a concern.
