CC is getting that 10... private network address from somewhere. Does the PRO have more than one network interface? Perhaps both WiFI and cellular? Or IP over bluetooth? It could be that when multiple networks are available CC is picking the wrong one.
Although my son works on iOS CC while I do the Android version, I am interesting in what is happening network-wise. If you could send me a CC debug log at cc_debug_logs AT haleys DOT org I would appreciate it. And who knows, I might actually see something useful.
