First three numbers are based on timestamp, so they will be monotonically increasing. The 1 before the most significant digits (in 11d8) of the timestamp indicates the UUID version, for time-based UUIDs this is 1.įourth and Fifth parts would be mostly constant if it is generated from a single server. When the timestamp has the (60 bit) hexadecimal value: 1d8 eebc 58e0a7d7. Nevertheless, a collision should have a very low probability. In this case, spatial uniqueness cannot be guaranteed. A random number is substituted if the latter is not available (for example, because the host computer has no Ethernet card, or we do not know how to find the hardware address of an interface on your operating system).
