How to find out the IP addresses PhotoSync uses to connect?
To find out which IP addresses PhotoSync Companion uses to connect with your Wi-Fi or wired network (e.g. to confirm that your PC and your iDevice are connected to the same subnet), there is an easy way to list your active network interfaces without going into the Windows settings.
Simply click on the small white PhotoSync icon in the taskbar at the bottom right to open the application menu and select About... from the menu.
The window About PhotoSync Companion displays the version number of your PhotoSync installation and all active network interfaces of your computer with the corresponding IP addresses (Internet addresses) used by PhotoSync and the communication channel (port). An IP address in the local network usually consists of an IPv4 address consisting of 4 numbers between 0 and 255 separated by a dot. In this example, the IP address is 192.168.100.129
