## What it is
A fork of the ENet reliable UDP networking library written in pure C, distributed as a single header. It adds IPv6 support, monotonic time, and code cleanup while providing optional reliable, in-order packet delivery and fragmentation over UDP.

## Use cases
- add reliable UDP networking to a C or C++ game
- send packets with reliable in-order delivery over UDP
- single-header networking library for a multiplayer game
- IPv6 support for ENet-based networking
- lightweight embeddable network communication layer
- fragment large packets over UDP connections

## When to choose
- you want a thin, portable, easily embeddable UDP layer with optional reliability
- you need IPv6 support or single-header distribution that upstream ENet lacks
- you're building real-time multiplayer games or low-latency communication in C/C++

## When to avoid
- you need higher-level features like authentication, encryption, lobbying, or server discovery
- you prefer the original upstream ENet with its long-term stability
- you need TCP-style streaming or HTTP-level networking

## Facets
- artifact type: library
- maturity: active
- function: networking, p2p
- domain: networking
- platform: cross-platform, cpp, c
- tags: udp, reliable-udp, header-only, single-header, ipv6, gamedev, enet-fork, lightweight, game-development, real-time
