# Subnetworks

Subnets are used to group your endpoints in the [Endpoints](https://docs.serenicity.fr/control/english/devices/dashboard-dun-appareil/peripheriques) section of the dashboard.

For example, to group endpoints from addresses `192.168.1.0` to `192.168.1.255`, you can set the following mask: `192.168.1.0/24`.

Here are some examples of masks with associated IP ranges.

| Mask             | IP range                      |
| ---------------- | ----------------------------- |
| `192.44.78.0/26` | `192.44.78.0 - 192.44.78.63`  |
| `10.0.25.0/24`   | `10.0.25.0 - 10.0.25.255`     |
| `172.16.0.0/12`  | `172.16.0.0 – 172.31.255.255` |
