  | Requirement | Sonar |
| --- | --- |
   | Supported Servers | [Velocity](https://papermc.io/downloads/velocity), [BungeeCord](https://ci.md-5.net/job/BungeeCord), [Paper (1.21+)](https://papermc.io/downloads/paper) |

In order to use Sonar, you will need

- an active, uninterrupted internet connection,
- unrestricted outbound access to the licensing server domain and port,
- a static external IP address. Enterprise customers are eligible for dynamic IP support.

Disclaimers

- Some significantly modified Minecraft clients (including cheats) may interfere with the verification process.
- Sonar skips players connecting through Geyser (via floodgate) and Eaglercraft (via EaglerXServer) by default.
- Compatibility with modified clients or servers and unofficial game versions can never be fully guaranteed.
- While Sonar attempts to block all bots, bypasses can occur, especially through the in-game verification.
