If you want to connect your PlayStation 4 to an Ethernet network without using a router, there are a few things you can do. First, make sure that your PlayStation 4 is connected to the internet. Then, open the Settings menu on your PlayStation 4 and select Network. Under “Network Type,” select “Ethernet.” Now, under “Ethernet Connection,” select “Manual.” Under “IP Address,” type in the IP address of the router or switch that you want to connect to your PlayStation 4. Under “Subnet Mask,” type in 255.255.255.0. Finally, under “Gateway Address,” type in the IP address of the router or switch that your PlayStation 4 is connected to. Now, under “Connection Type,” select “Static IP.” Under “Primary DNS Server,” type in the IP address of the primary DNS server for your network. Under “Secondary DNS Server,” type in the IP address of a secondary DNS server for your network. Finally, under “Proxy Server” enter http://proxy-server-address:8080/ into your web browser (for example http://192.168.1.1:8080/). This will allow you to use online services like Netflix and Hulu without having to enter their login information each time you want to use them. ..
