As stated in SCNetwork.h,
The term "reachable" reflects whether a data packet, sent by
an application into the network stack, will be able to reach
the destination host.
Please note that being able to reach the destination host
does not guarantee that the data packet will reach the
host.
That is, the "reachability" status is a function of current network
configuration, not the result of communications activity. Reachability
answers a question like "is there an enabled, active interface with a
route to this address?".
