DDoS attacks come in three broad families: volumetric floods that saturate your pipe, protocol attacks that exhaust connection state, and application-layer floods that look like legitimate traffic. Each one exhausts a different resource, so each one needs a different defence, and no single layer stops all three. This guide maps the common attack forms to the resource they target and the mitigation that actually works against them, explains what an on-host firewall can and cannot stop, and ends with a practical incident-response runbook for when your server is under fire.

Ping is only part of what a player feels. A single round trip runs through input sampling, the last mile, transit and peering, a queue on the server, and the wait for the next simulation tick before the world reacts at all. This guide breaks down where felt delay actually comes from, how tick rate and netcode change the picture, why jitter and packet loss hurt more than a stable higher ping, and the one lever a host controls most: putting the server close to players on hardware that holds its tick rate.
