What DNS servers are used when connected to wireless data? What DNS servers are used when connected to wireless data (not wifi)?

Is there a way within Android KitKat to tell?
While the setprop method to change DNS does not work, the getprop method to read those values should be still valid today:

shell@A0001:/ $ getprop | grep dns
[dhcp.wlan0.dns1]: [192.168.1.1]
[dhcp.wlan0.dns2]: []
[dhcp.wlan0.dns3]: []
[dhcp.wlan0.dns4]: []
[net.change]: [net.rmnet0.dns2]
[net.dns1]: [208.67.222.123]
[net.dns2]: [208.67.220.123]
[net.rmnet0.dns1]: [208.67.222.123]
[net.rmnet0.dns2]: [208.67.220.123]
[net.wlan0.dns1]: [208.67.222.123]
[net.wlan0.dns2]: [208.67.220.123]


To clarify my answer: using a terminal emulator app (like Terminal Emulator for Android), as a normal user (no root permissions needed), you can execute the command I showed (getprop | grep dns) and get an output like that.
