MC-Networking

by AsgarraRu

MC-Networking lets players build, configure and simulate real IP networks with devices and protocols inside the game world.

FabricClient and serverMIT LicenseOpen source26.2 – 26.3

What it does

Networking devices are added as blocks that represent hardware, and network cables are added as items that physically link the machines to one another. Players build a network out of these parts and then work with the simulated devices from inside the game.

The simulation covers host and networking devices up to ISO/OSI layer 3, with ARP and MAC address resolution and encapsulation and decapsulation of payloads between layers. A simulated server forwards packets in sync across interfaces, exit queues, transmission and propagation. Interacting with a device opens an emulated custom CLI in the game interface, used to configure and diagnose it. The project is aimed at teaching networking as an interactive tool, and it is still under development.

Fabric API is required. The mod is open source under the MIT License and its source code, issue tracker and wiki are publicly available. A server running it needs every connecting player to have it too. Files are published for Fabric only, for game versions 26.2 and 26.3, and the latest file is v1.1.3-26.3 for 26.3, dated 2026-09-29.

Key features

  1. Hardware device blocks

    Blocks stand in for networking hardware, so each device occupies a place in the world and can be linked to others.

  2. Network cable items

    Cable items join devices together physically, turning placement into an actual topology.

  3. Layer 3 host simulation

    End devices are simulated up to ISO/OSI layer 3, including encapsulation and decapsulation of payloads.

  4. ARP and MAC resolution

    Devices resolve addresses through ARP and MAC address lookup as part of the simulated network engine.

  5. Emulated CLI

    Main CLI commands run inside the game interface to configure and diagnose a selected device.
