Properties

Property Numbering

While the majority of the properties that allow the configuration of network connectivity are network protocol specific, there are several properties that are required in all implementations.

Future property allocations SHALL be made from the following allocation plan:

Property ID Range	Description
0 - 127	Reserved for frequently-used properties
128 - 15,359	Technology-specific
15,360 - 16,383	Vendor-specific
16,384 - 1,999,999	Technology-specific
2,000,000 - 2,097,151	Experimental use only

For an explanation of the data format encoding shorthand used throughout this document, see (#data-packing).

Property Sections

The currently assigned properties are broken up into several sections, each with reserved ranges of property identifiers. These ranges are:

Name	Range (Inclusive)	Description
Core	0x000 - 0x01F, 0x1000 - 0x11FF	Spinel core
PHY	0x020 - 0x02F, 0x1200 - 0x12FF	Radio PHY layer
MAC	0x030 - 0x03F, 0x1300 - 0x13FF	MAC layer
NET	0x040 - 0x04F, 0x1400 - 0x14FF	Network
Thread	0x050 - 0x05F, 0x1500 - 0x15FF	Thread
IPv6	0x060 - 0x06F, 0x1600 - 0x16FF	IPv6
Stream	0x070 - 0x07F, 0x1700 - 0x17FF	Stream
MeshCop	0x080 - 0x08F, 0x1800 - 0x18FF	Thread Mesh Commissioning
OpenThread	0x1900 - 0x19FF	OpenThread specific
Interface	0x100 - 0x1FF	Interface (e.g., UART)
PIB	0x400 - 0x4FF	802.15.4 PIB
Counter	0x500 - 0x7FF	Counters (MAC, IP, etc).
Nest	0x3BC0 - 0x3BFF	Nest (legacy)
Vendor	0x3C00 - 0x3FFF	Vendor specific
Debug	0x4000 - 0x43FF	Debug related
Experimental	2,000,000 - 2,097,151	Experimental use only

Note that some of the property sections have two reserved ranges: a primary range (which is encoded as a single byte) and an extended range (which is encoded as two bytes). properties which are used more frequently are generally allocated from the former range.
