# Subnets configuration for arp-scan
# Subnets configuration
You need to specify the network interface and the network mask. You can also configure multiple subnets and specify VLANS (see exceptions below).
> [!TIP]
> You may need to increase the time between scans `ARPSCAN_RUN_SCHD` and the timeout `ARPSCAN_RUN_TIMEOUT` settings when adding more subnets. If the timeout setting is exceeded, the scan is cancelled to prevent application hanging from rogue plugins. Check [debugging plugins](/docs/DEBUG_PLUGINS.md) for more tips.
> You may need to increase the time between scans `ARPSCAN_RUN_SCHD` and the timeout `ARPSCAN_RUN_TIMEOUT` (and similar setting on related plugins) when adding more subnets.

## Examples
> [!NOTE]
> Please use the UI to configure settings as that ensures that the config file is in the correct format. Edit `app.conf` directly only when really necessary.

* Examples for one and two subnets (❗ Note the `['...','...']` format):
* One subnet: `SCAN_SUBNETS = ['192.168.1.0/24 --interface=eth0']`
* Two subnets: `SCAN_SUBNETS = ['192.168.1.0/24 --interface=eth0','192.168.1.0/24 --interface=eth1 -vlan=107']`
* One subnet: `SCAN_SUBNETS = ['192.168.1.0/24 --interface=eth0']`
* Two subnets: `SCAN_SUBNETS = ['192.168.1.0/24 --interface=eth0','192.168.1.0/24 --interface=eth1 -vlan=107']`
## Explanation
@@ -27,7 +27,7 @@ The arp-scan time itself depends on the number of IP addresses to check.
> The number of IPs to check depends on the [network mask](https://www.calculator.net/ip-subnet-calculator.html) you set on the `SCAN_SUBNETS` setting.
> For example, a `/24` mask results in 256 IPs to check, whereas a `/16` mask checks around 65,536. Every IP takes a couple of seconds. This means that with an incorrect configuration, the arp-scan will take hours to complete instead of seconds.
Specify the network filter (which **significantly** speeds up the scan process). For example, the filter `192.168.1.0/24` covers IP ranges 192.168.1.0 to 192.168.1.255.
