==== Version 8 (custom) ====
Version 8 only has two requirements:

* The variant bits have to be <code>10</code>, so the nibble containing the variant must be 8 (<code>0b1000</code>), 9 (<code>0b1001</code>), A (<code>0b1010</code>), or B (<code>0b1011</code>).
* The version nibble has to be the value of 8.

Those requirements tell the system that it is a version 8 UUID. The remaining 122 bits are up to the vendor to customize. The difference with version 4 is that those 122 bits are random, but the 122 bits in UUID version 8 are not, because they follow vendor specific rules.
