.SS Network namespaces (CLONE_NEWNET)
Network namespaces provide isolation of the system resources associated
with networking: network devices, IPv4 and IPv6 protocol stacks,
IP routing tables, firewalls, the
.I /proc/net
directory, the
.I /sys/class/net
directory, port numbers (sockets), and so on.
A physical network device can live in exactly one
network namespace.
A virtual network

device pair provides a pipe-like abstraction
.\" FIXME . Add pointer to veth(4) page when it is eventually completed
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.
.PP
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).
.PP
Use of network namespaces requires a kernel that is configured with the
.B CONFIG_NET_NS
option.
