# Internet
Internet is a network library that provides encoding, structure mapping, communication primitives and implementations of network standards, protocols and algorithms in one place.
> **Development Status — August 2026**
>
> The project is days old. Much of the current roughness consists of "hot pie" defects — surface imperfections that smooth out as the codebase cools.
>
> We expect the API to harden significantly by **20 August 2026**. Until then, **treat every release as potentially breaking** and pin your dependency to an exact version if you are experimenting early.
## Protocol Support
> **How to read this table**
>
> | Legend | Meaning |
> | -------- | --------- |
> | **Phase** | |
> | ✅ **Supported** | Ready for use. The API is stabilized and covered by tests. |
> | ❄️ **Cooling** | Nearly ✅ **Supported** |
> | 🚧 **Developing** | Actively worked on. Core functionality is there, but with known limitations. |
> | 📋 **Planned** | Next in queue. Development has not started yet. |
> | **Encoding / Mapping** | |
> | `Complete` | Implemented and tested. |
> | `Partial` | Available but incomplete (draft quality or missing features). |
> | `Planned` | Will be delivered when the protocol reaches the front of the queue. |
> | **Stability** | |
> | `Stable` | Production-ready, API frozen. |
> | `Beta` | Mostly complete, minor API changes possible. |
> | `Alpha` | Functional, but expect breakage. |
> | `Experimental` | Exists, but not yet verified or battle-tested. |
> | `Unstable` | Under active refactoring; things will move around. |
