  "why_use_this": "libslirp is a dependency for hypervisors and emulators (QEMU, etc.) that need lightweight user-space networking without requiring root privileges or host kernel modules. It implements a full TCP/IP stack in userland, making it essential for VM and container runtimes that provide isolated network namespaces."
