node property

int get node

The spatially unique node identifier.

Definition from RFC 4122

For UUID version 1, the node field consists of an IEEE 802 MAC address, usually the host address. For systems with multiple IEEE 802 addresses, any available one can be used. The lowest addressed octet (octet number 10) contains the global/local bit and the unicast/multicast bit, and is the first octet of the address transmitted on an 802.3 LAN.

For systems with no IEEE address, a randomly or pseudo-randomly generated value may be used; see Section 4.5. The multicast bit must be set in such addresses, in order that they will never conflict with addresses obtained from network cards. For UUID version 3 or 5, the node field is a 48-bit value constructed from a name as described in Section 4.3.

For UUID version 4, the node field is a randomly or pseudo-randomly generated 48-bit value as described in Section 4.4.
