On the other hand, UUID version 4 uses random generation based on pseudo-random numbers. This method ensures UUID uniqueness without requiring checking the system clock or the MAC address. It also has the advantage of not revealing information about the machine generating the UUID. However, it is important to choose a reliable source of pseudo ...
Although the random UUID uses random bytes, four bits are used to indicate version 4, while two to three bits are used to indicate the variant. These can be created using a random or pseudo-random number generator. More bits are used in this version, so there are fewer UUID combinations. However, there are still enough UUID combinations to ...

An online UUID version 1 generator uses JavaScript to generate a random number and combine it with the current timestamp and the MAC address of the user's device. The result is a unique 128-bit identifier in the format of xxxxxxxx-xxxx-1xxx-yxxx-xxxxxxxxxxxx, where x represents a hexadecimal digit and y is either 8, 9, A, or B.
UUID Version-3 Generator. The namespace must be a valid UUIDs in the format 00000000-0000-0000-0000-000000000000. Toggle the switch above to select a pre-defined UUID or autofill with random UUID. Select pre-defined UUID identifier. We translate the selected identifier to the corresponding well-known UUID internally.

I really like how clean Broofa's answer is, but it's unfortunate that poor implementations of Math.random leave the chance for collision.. Here's a similar RFC4122 version 4 compliant solution that solves that issue by offsetting the first 13 hex numbers by a hex portion of the timestamp, and once depleted offsets by a hex portion of the microseconds since pageload.
This specification defines UUIDs (Universally Unique IDentifiers) -- also known as GUIDs (Globally Unique IDentifiers) -- and a Uniform Resource Name namespace for UUIDs. A UUID is 128 bits long and is intended to guarantee uniqueness across space and time. UUIDs were originally used in the Apollo Network Computing System (NCS), later in the Open Software Foundation's (OSF's) Distributed ...

Figure 1 : IPv6 ULA-UUID Address Format. To form an IPv6 ULA-UUID, the node creates a 128-bit UUIDv4 per [ RFC9562] then simply replaces the most significant 8 bits with the constant string '11111100' (0xfc); the resulting 128-bit ULA-UUID then has the format of an IPv6 address with an 8-bit subnet prefix and 120-bit interface identifier as ...
