# Scan
> Manual and automatic scanning to add new miners to Nonce
When new miners are deployed or the network changes, scan to add miners to Nonce. Both manual and automatic scanning are supported.
## Manual Scan
1. On the [Miners](https://nonce.app/demo/farms/a28185a3-791f-4057-a318-0b4c156b00d8/miners) page, click the scan button.
2. Confirm the IP range and click confirm.
3. Wait for the scan Task to complete.
## How to Determine IP Range
When configuring scan IP ranges, consider:
* **Check router/switch**: View DHCP or static IP address ranges on the gateway
* **Check existing miner IPs**: Use IPs of miners already in the farm to infer other addresses in the same subnet
* **Follow network plan**: If the datacenter has VLAN or subnet planning, use subnets (e.g., 192.168.1.0/24)
* **Avoid large ranges**: Large ranges may take longer; consider scanning by rack or zone
## Automatic Scan
Once configured, the system scans specified IP ranges on a schedule. New miners are discovered automatically.
1. Go to the [Settings](https://nonce.app/demo/farms/a28185a3-791f-4057-a318-0b4c156b00d8/settings/scan) page and open the Scan tab.
2. Add IP ranges under auto scan.
3. Click the scan miners button to enable auto scan.
