#uuid ⇒ Object

Documentation on PBXObjectId by @tjw lists.apple.com/archives/projectbuilder-users/2003/Jan/msg00263.html

ObjectId gets generated in the following format: ---------------------------------------------------------------------- | RANDOM | SEQ | TIME | PID | IP (2) | | byte byte | byte byte | byte byte byte byte | byte byte | byte byte | ---------------------------------------------------------------------- RANDOM = 2 bytes of random number for distribution SEQ = Unsigned short sequence counter that starts randomly. TIME = Seconds since epoch (1/1/1970) PID = Process ID

This is only two bytes even though most pids are longs.
Here you would take the lower 2 bytes.

IP = IP Address of the machine (subnet.hostId)
