Version 4 is made up of random bits based on the timestamp of the system that generates them. The timestamp is usually shown in microseconds (one thousandth of a second) since a specific date (called EPOCH). The result is therefore pseudo-random and presents a very probable uniqueness (not guaranteed). Each time a UUID v4 is generated, the code generated is different.
Example: UUID v4 0cc12fda-deca-4f24-918b-f0884d2bb911
Each time a v3 or v5 UUID is generated, the generated code is always the same.
The UUID code contains 128 bits presented in the form of 32 hexadecimal characters divided into 8-4-4-4-12 digits (base 16) and separated by a dash -
