Linux Networking
Linux networking is the kernel network stack and the tools that configure it. It gives processes interfaces, addresses, routes, name resolution, and packet-filtering paths so they can communicate with local and remote systems.

Linux networking is a packet path, not a single service. The kernel gives each network context interfaces, addresses, routes, sockets, and packet-filtering state. User-space tools inspect and change that state.
