Here’s something most people don’t find out until it’s too late: your IP address isn’t just some random string of numbers. It’s a digital home address. And when you’re gaming on public Wi-Fi without a VPN, you’re basically shouting it across the room.
In older Call of Duty games, for example, the lobby system used peer-to-peer (P2P) connections — meaning your device was talking directly to other players’ devices, not through a protected server. Skilled players who knew what they were doing could pull your IP address just from being in the same lobby as you — particularly back when VPNs were less common. Minecraft has the same issue with private servers. And this wasn’t some crazy hacker trick — it was just how those games worked.
So what can someone actually do with your IP? Quite a bit. They can use it to estimate your physical location. They can hit you with a DDoS attack — basically flooding your internet connection with so much garbage traffic that it crashes, kicking you offline or making your whole household’s internet go dark. And in extreme cases, bad actors have used IP addresses to find someone’s general area and send a fake emergency call to police — that’s called swatting, and it’s gotten people killed.
DDoS attacks are a particular threat during gaming sessions, and a VPN helps by hiding your real IP address — the other players (or whoever’s watching the lobby) only see the VPN server’s address instead of yours.
Public Wi-Fi makes all of this worse. On a home network, you’ve got some natural protection from your router. On public Wi-Fi, that buffer is thinner, and the network itself might not be trustworthy. There’s also the risk of rogue networks — fake Wi-Fi hotspots set up to look like the real café or library network — that can monitor everything flowing through them.
The fix is pretty simple: use a VPN when gaming on public Wi-Fi. It masks your IP, which cuts off the main thing someone would need to DDoS you, track your location, or set up anything worse. If you’re already being targeted and things feel out of hand, connecting through a VPN to change your visible IP address is one early step that can help — though it won’t instantly stop an attack already underway. For serious or ongoing threats, reporting to somewhere like the FBI’s Internet Crime Complaint Center is an option too.
Not every random online opponent is a threat. Most people just want to play. But it only takes one person with bad intentions and the right tools to ruin your day — or worse. Knowing how this works means you can protect yourself without paranoia.
