The essential points from this guide -- each one is explained in detail below.
The PS4 proxy server option sits inside Settings > Network > Set Up Internet Connection > Custom > Proxy Server.
It asks for a proxy address and a port number, both supplied by whoever runs the proxy or network.
Leaving it on "Do Not Use" is correct for almost every home gaming connection.
PS5 keeps the same menu path; Nintendo Switch labels the setting differently but serves the same purpose.
A proxy rarely improves PS4 latency or matchmaking speed, since routing through an extra server usually adds delay.
Sony buried the proxy server option a few menus deep because most players never need to touch it. From the PS4 home screen, open Settings, then Network, then Set Up Internet Connection. Pick either Wi-Fi or LAN cable, then choose Custom instead of Easy. Custom setup walks through IP address, DHCP host name, DNS settings, and MTU settings before it finally reaches the Proxy Server screen near the end.
That screen is what answers "what is a proxy server ps4": a two-option prompt, "Do Not Use" or "Use." Selecting "Do Not Use" tells the console to connect directly to PlayStation Network with no intermediary server. Selecting "Use" opens two additional fields, Address and Port, which the console needs before it can finish the connection test.
This single screen is also the answer to "what is proxy server ps4" in the sense most people mean it: it is not a feature that unlocks something extra, it is a network routing option carried over from the days when many corporate and school networks required a proxy for any device to reach the internet at all.
If you do have a reason to use a proxy, PS4 asks for exactly two values on the Proxy Server screen: Address and Port. The address is either an IP address (like 192.168.1.50) or a hostname (like proxy.company.com), and the port is a number, commonly 8080, 3128, or 80 depending on the proxy server's configuration.
This is the direct answer to "proxy server address ps4" and "ps4 proxy server address": there is no universal address that works for every console. The address belongs to whichever proxy server you are actually trying to connect through, so you get it from your network administrator, your workplace IT team, or the documentation for the specific proxy service you are using. Typing in a random address or a public proxy IP will not connect you to PlayStation Network faster or unlock anything; it will most often just fail the connection test.
After entering both fields, PS4 runs its standard internet connection test, checking Internet Connection, NAT Type, and PlayStation Network sign-in status. If the proxy address or port is wrong, the test fails at the Internet Connection step and the console falls back to reporting a connection error rather than silently skipping the proxy.
This setting exists for network environments that require a proxy for every connected device, not for regular home gaming. Offices, schools, dorms, and some public Wi-Fi networks route all traffic through a proxy server for filtering, logging, or content control. If your PS4 sits on one of those networks, IT staff will usually tell you the address and port to enter here.
That answers "what is the proxy server for ps4" for the vast majority of people asking it: it is a corporate/restricted-network setting, and a typical home router does not require one. Turning it on without a real proxy address, or entering incorrect values, breaks your console's connection to PlayStation Network entirely. You will see connection failures during the network test, and PSN sign-in, game downloads, and online play will all stop working until you set it back to "Do Not Use."
If your home internet works fine on "Do Not Use" (which it does for almost every residential ISP connection), there is no reason to change it. This setting will not fix NAT Type issues, will not speed up downloads, and will not reduce matchmaking lag on a standard home network.
"Proxy server ps5" leads to nearly the same menu as PS4. On PS5, go to Settings > Network > Settings > Set Up Internet Connection, choose your connection type, select Advanced Settings, and the Proxy Server option appears with the same Do Not Use / Use choice and the same Address and Port fields. Sony kept the layout consistent across both consoles, so anything true for PS4 proxy setup applies to PS5 as well.
"Proxy server switch" points to a different path, since Nintendo does not label the option "Proxy Server" the same way. On Nintendo Switch, open System Settings, then Internet, then Internet Settings, select your network, choose Change Settings, and look for the Proxy Server field near the bottom, below DNS Settings. Functionally it works the same way: enter an address and port only if a specific network requires it, and leave it off for standard home Wi-Fi.
A proxy on PS4 has a narrow set of legitimate use cases, and none of them involve making matchmaking or downloads faster. The main scenario is network access: connecting through a network that mandates a proxy for any internet-bound traffic, such as a corporate guest network or certain school residence networks. In that case the proxy is not optional, it is the only way the console reaches PlayStation Network at all.
A second scenario is basic network testing, where IT staff or advanced users route console traffic through a proxy temporarily to inspect connection behavior or confirm a firewall rule. This is a diagnostic use, not a performance upgrade.
What a proxy will not do is lower ping, improve NAT Type, or speed up matchmaking. Adding a proxy server inserts an extra hop between your console and PlayStation Network, which typically adds latency rather than removing it. If your goal is faster or more stable connections for online play, the proxy server setting is the wrong tool. Router-level fixes (port forwarding, wired connection, correct DNS), not console proxy settings, are what actually affect PS4 network performance.
