Is there any way to generate the same UUID from a string stack?
(In a way, the namespace acts like a seed would, for a random number generator. By contrast, while a seed is supposed to be random, our namespace is a constant. And that forces our generator to always produce the same value for a given input.)

Which is an example of a host based UUID?
In the UUID 00000000-0000-0000-0000-000000000000, all bits are set to zero. UUIDs v1, also known as host or time based UUIDs, are generated taking into consideration different components. Take for example, the following UUID v1:
Why are UUIDs generated every time they are generated?
You are guaranteed to get unique UUIDs every time they are generated. An attacker may be able to get the exact timestamp, clock sequence and node (MAC address) of the system from an arbitrary UUID – Cost of anonymity. If an attacker is in possession of previous UUIDs generated from a system, it’s much easier to predict future ones.
How many octets are there in a UUID?
The 16 octets of a UUID are represented as 32 hexadecimal digits and separated by hyphens into five groups, in the form 8-4-4-4-12. This results in a total of 32 alphanumeric characters and 4 hyphens. See the UUID v1 example below: M: Indicates the UUID version.
