Here's what happens.

If in my location, all the Network Ports are disabled, SCNetworkCheckReachabilityByAddress returns 0 in its flags. This is > ok.

Now if all the Network Ports are enabled :
If Ethernet is enabled and the link is up, it also returns 0 in its flags. This is not ok. The address can be reached.

Can you send/post the output from the "ifconfig -a", "netstat -rn", and "scutil -d -r address-being-queried" commands.

If PPP is enabled and disconnected, the flags are transient, reachable and connectionRequired.
Why do I have reachable here ?

Because you have a PPP ("transient") connection which, if established ("connection required"), could provide access ("reachable") to the target host/address.

If PPP is connected, flags are 0. I should have reachable here.

Again, the output from the "ifconfig", "netstat", and "scutil" commands would help explain your results.

Is it a bug ?

Dunno yet.
