42.\fB nsIPC \*(Em IPC namespace \fR
The Inode of the namespace used to isolate interprocess communication (IPC)
resources such as System V IPC objects and POSIX message queues.
.TP 4
43.\fB nsMNT \*(Em MNT namespace \fR
The Inode of the namespace used to isolate filesystem mount points thus
offering different views of the filesystem hierarchy.
.TP 4
44.\fB nsNET \*(Em NET namespace \fR
The Inode of the namespace used to isolate resources such as network devices,
IP addresses, IP routing, port numbers, etc.
.TP 4
45.\fB nsPID \*(Em PID namespace \fR
The Inode of the namespace used to isolate process ID numbers
meaning they need not remain unique.
Thus, each such namespace could have its own 'init' (PID #1) to
manage various initialization tasks and reap orphaned child processes.
.TP 4
46.\fB nsUSER \*(Em USER namespace \fR
The Inode of the namespace used to isolate the user and group ID numbers.
Thus, a process could have a normal unprivileged user ID outside a user
namespace while having a user ID of 0, with full root privileges, inside
that namespace.
.TP 4
47.\fB nsUTS \*(Em UTS namespace \fR
The Inode of the namespace used to isolate hostname and NIS domain name.
UTS simply means "UNIX Time-sharing System".
