I was playing around with my Samsung TV trying to hide other network UPnP/DLNA devices such as Sonos speakers from showing up as source inputs on the TV.
I figured I would manually configure my TV to be on a separate subnet from those other devices but I ended up just setting a manual IP address (192.168.1.66) and subnet mask of 255.255.255.255 along with the gateway IP (192.168.1.1) and it actually works!! I can’t understand how or why.
The DLNA devices are no longer showing up as inputs and more importantly the internet is still working on the TV. How can the internet be working if a subnet mask of 255.255.255.255 only allows for one host which should mean that my TV shouldn’t be able to reach the gateway.
I guess I’d like to understand how or why it’s working.
