DDoS Protection for Game Servers: What Dedicated Hosting Providers Offer

Game servers are the most attacked workloads in hosting, and the attacks are getting bigger. A public ARK or Rust server IP gets scanned within hours of going live, and a grudge match between communities can turn into a multi-hundred-gigabit flood that no home connection survives. What actually protects you depends on what your dedicated hosting provider offers — and the difference between “we filter DDoS” and “we null-route your IP at the first spike” is the difference between a playable server and a dead one. Here is what to look for, and what the tiers of protection really mean.

As you compare providers, compare dedicated server plans with their DDoS terms side by side — the mitigation tier is often buried in the contract, and it varies more than the hardware does.

L3/L4 versus L7: which attacks hit game servers

Attacks come in two broad families, and game servers are unusually exposed to both:

• L3/L4 volumetric attacks flood the network or transport layer — UDP floods, SYN floods, and reflection/amplification (DNS, NTP, memcached) that can exceed hundreds of gigabits per second. Game traffic is UDP, which makes game servers natural targets for UDP floods that must be scrubbed at the network edge.
• L7 application-layer attacks target the game or its services directly — connection floods, login request storms, and HTTP floods against any web-facing panel or query endpoint. They are smaller in bandwidth but harder to filter, because the traffic looks legitimate at the packet level.

Always-on versus on-demand mitigation

The most important question to ask a host is not “do you offer DDoS protection” but “is it always on, or do you turn it on when attacked?” On-demand protection has a detection gap: the attack must be noticed, escalated, and scrubbed before traffic is cleaned, and during that window your server is down or your IP is null-routed. Always-on filtering sits in the path continuously, so attacks are absorbed without a human in the loop — at the cost of a little added latency on every packet, including legitimate ones.

Factor	Always-on filtering	On-demand mitigation
Time to protection	Instant — traffic is scrubbed continuously	Minutes to hours after detection
Attack window	None	Every attack until it is escalated
Latency impact on players	Small added hop; negligible on anycast	None when idle
Cost	Higher, often bundled into the plan	Lower, sometimes free but limited
Best fit	Public 24/7 game communities, competitive servers	Small private servers, low attack risk

What to verify with a provider

• Mitigation capacity: Ask for the scrubbing capacity in Tbps. A provider that claims “DDoS protection” without a number is often running a few hundred Gbps of filtering — enough for small attacks, useless against the big floods that target popular servers.
• Scrubbing trigger: What threshold flips traffic into the scrubber? If the trigger is high, short attacks may never engage it.
• Null-routing policy: The worst case is a host that null-routes your IP at the first sign of attack — that “protects” the network by killing your server. Confirm in writing that the response is scrubbing, not blackholing.
• Port and protocol coverage: Game servers run on UDP ports; some filters cover TCP and HTTP well but handle UDP floods poorly. Confirm UDP flood mitigation specifically.
• Anycast network: Providers on an anycast network absorb and disperse attacks across multiple PoPs, which is why big game hosts all route through one.
• Post-attack behavior: What happens after an attack ends — does filtering stay hot, and is there any cap on how many attacks are covered per month?

What dedicated hosting providers typically offer

Dedicated hosting DDoS protection comes in three rough tiers. Entry-level plans usually include basic edge filtering — enough to absorb small volumetric attacks, often with a low capacity cap and on-demand behavior. Mid-tier plans add always-on scrubbing with real capacity and UDP coverage, which is what most public game communities should target. Top-tier setups add dedicated mitigation appliances, higher capacities, and sometimes per-port filtering rules. The honest way to evaluate a plan is to ask what happens to your server during a real attack — not what the marketing page says about “enterprise-grade protection.”

You can also reduce your attack surface yourself: keep your server IP off public Discord listings, use firewall rules that drop everything except your game ports, cap connection rates at the OS level, and never expose RDP or SSH to the internet on default ports. None of that replaces provider-level mitigation, but it shrinks the number of attacks you attract in the first place. For a deeper look at matching protection to your setup, check dedicated server hosting plans with DDoS protection included.

If you want always-on filtering with real capacity rather than a null-route reflex, review InterServer’s dedicated server DDoS protection — their plans bundle mitigation and specify the terms in writing instead of leaving the response to chance.
