I don't think there is a way to view the address on the KPA itself. You have to look at the list of assigned client IP-address for your DHCP-server. Usually that means that you have to examine the status of the DHCP-server built into your home router which is the most common source of DHCP on a home network.
No. You can find your IP in the System Menu
-System Menu
-Page 12/12
-Details
-now the IP shows in the left, dark part of the screen.
!! it is only visible when the KPA is connected via network cable !!
