advanced use case would be changing the host's hostname from a container.
## <a name="ipc"></a> IPC settings (--ipc)

--ipc="MODE" : Set the IPC mode for the container
```
The `--ipc` flag accepts the following values:
| Value | Description |
|:---------------------------|:----------------------------------------------------------------------------------|
| "" | Use daemon's default. |
| "none" | Own private IPC namespace, with /dev/shm not mounted. |
| "private" | Own private IPC namespace. |
| "shareable" | Own private IPC namespace, with a possibility to share it with other containers. |
| "container:<_name-or-ID_>" | Join another ("shareable") container's IPC namespace. |
| "host" | Use the host system's IPC namespace. |
If not specified, daemon default is used, which can either be `"private"`
or `"shareable"`, depending on the daemon version and configuration.
IPC (POSIX/SysV IPC) namespace provides separation of named shared memory
segments, semaphores and message queues.
Shared memory segments are used to accelerate inter-process communication at
memory speed, rather than through pipes or through the network stack. Shared
memory is commonly used by databases and custom-built (typically C/OpenMPI,
C++/using boost libraries) high performance applications for scientific
computing and financial services industries. If these types of applications
are broken into multiple containers, you might need to share the IPC mechanisms
of the containers, using `"shareable"` mode for the main (i.e. "donor")
container, and `"container:<donor-name-or-ID>"` for other containers.
