What is a DDoS-protected IP for game servers?

Quick answer

If you host a game server, “DDoS protection” is a feature you’ll see advertised — and a real concern, since game servers are common targets. Here’s what a DDoS-protected IP actually means and how the protection works.

The threat it addresses

A DDoS (Distributed Denial-of-Service) attack floods a server with junk traffic from many sources at once, overwhelming its connection so legitimate players can’t get through — the server effectively goes offline. Game servers attract these from disgruntled players, rivals, or extortion attempts, which is why hosts offer protection.

How a protected IP works

A DDoS-protected IP routes incoming traffic through a scrubbing/mitigation layer before it reaches your server. That layer absorbs and filters attack traffic — using large network capacity and detection systems to drop the flood — while passing legitimate player connections through. Players connect to the protected (advertised) IP; the real server sits behind the mitigation, shielded.

Why hiding the origin matters

Protection only holds if attackers can’t bypass it by hitting the real server directly. So a protected setup also hides the origin IP — players and attackers see the mitigation layer’s address, not the server’s true one (similar to how Cloudflare hides an origin). If the origin leaks, an attacker can route around the protection, which is why guarding it is critical.

What this means if you host

If you run a game server and face attacks, options include a host that offers DDoS-protected IPs, a protection service in front of your server, or for smaller setups, a tunnelling service that both sidesteps CGNAT and hides your home IP. Never expose your home IP directly for a public server you expect to be targeted — a flood aimed at it disrupts your whole connection, not just the game.

Checking what’s exposed

Confirm what address your server presents with our Bulk IP Audit tool or curl checkmyipnow.com/ip from the box. If the protected setup is working, the world should see the mitigation provider’s IP, not your origin. A leaked origin is the most common reason “protected” servers still go down.
