slirp4netns

slirp4netns is a networking tool designed to provide lightweight, user-mode networking for containers and virtual machines (VMs) by leveraging the SLIRP (SLIP Redirector Protocol) protocol. Introduced in [https://github.com/rootless-containers/slirp4netns 2019], slirp4netns enables containers and VMs to access the network without requiring elevated privileges or kernel modifications, making it suitable for use cases where root access is restricted or security is a concern. The tool creates a virtual network stack for each container or VM, allowing them to communicate with the host system and external networks using NAT (Network Address Translation). slirp4netns is commonly used in containerization platforms such as Docker, Podman, and Kubernetes to provide isolated networking environments for applications and services. By enabling user-mode networking, slirp4netns simplifies the deployment and management of containers and VMs while enhancing security and resource efficiency.
