RPL networks consists of leafs and routers. Both typically act as hosts.
Routers are just hosts that happen to be between other nodes.
(Although, some hosts are too weak to be routers)
Little to no traffic on the RPL is unaware of which RPLinstanceID to
use, because the applications there needs to send using a specific set
of constraints, which is encapsulated into the RPLinstanceID.
For ignorant applications, the OS may well be able to set the
instanceID. In other cases, an instanceID of zero may be most correct.
There may be some cases where there are ordinary hosts which are on a
network which is not RPL, but is connected to an RPL network.
(The group does not have any consensus if these will be layer-2 bridged,
or layer-3 routed yet). In these cases the application either will be
aware, or won't care.
