NETWORK_NAMESPACES(7) Linux Programmer's Manual NETWORK_NAMESPACES(7)
NAME
network_namespaces - overview of Linux network namespaces
DESCRIPTION
Network namespaces provide isolation of the system resources associated with networking: network devices, IPv4 and IPv6 protocol stacks, IP
routing tables, firewall rules, the /proc/net directory (which is a symbolic link to /proc/PID/net), the /sys/class/net directory, various
files under /proc/sys/net, port numbers (sockets), and so on. In addition, network namespaces isolate the UNIX domain abstract socket
namespace (see unix(7)).
A physical network device can live in exactly one network namespace. When a network namespace is freed (i.e., when the last process in the
namespace terminates), its physical network devices are moved back to the initial network namespace (not to the parent of the process).
A virtual network (veth(4)) device pair provides a pipe-like abstraction that can be used to create tunnels between network namespaces, and
can be used to create a bridge to a physical network device in another namespace. When a namespace is freed, the veth(4) devices that it
contains are destroyed.
Use of network namespaces requires a kernel that is configured with the CONFIG_NET_NS option.
