First checks gateway addresses (e.g. .1, .254). If none respond, the network is skipped to save time.
Example: When scanning the network 192.168.1.1-255, the expected gateway addresses specified in this field will be checked first. For example, if ".1" is specified in this field, the gateway whose address ends with this value will be checked—that is, 192.168.1.1. If this and the other specified gateways are unavailable, the remaining network addresses from 1 to 255 will not be checked. This significantly speeds up the scan.

Click “Start” to scan your local network and detect available devices (routers, cameras, web interfaces, etc.).
By using this service, you agree to the Terms and Conditions and Privacy Policy.
Safe and confidential
Yes. All scanning is performed locally in your browser. No scan results are sent to any server. The results remain only with you and are not stored anywhere.
The service does not have direct access to your network and cannot inspect devices. It does not collect or determine:
- MAC addresses
- device type
- manufacturer
- device model or name
In practice, the service only observes whether a response is received and how long it takes.
Even if the browser grants access to the local network, this does not provide the website with additional visibility into devices.
You fully control which IP addresses and ports are scanned.
How does it work?
Your browser sends HTTP/HTTPS requests to specified IP addresses and ports and checks whether a response is received.
If a response is received, the service assumes that a device exists at that address.
This means:
- Uses standard web requests (same as opening a website)
- No low-level network scanning or device access
- Only response timing is observed, not device details
- Some requests may be blocked by the browser (PNA)
Examples of use
- Find IP addresses of devices in your local network
- Check if a router or camera web interface is accessible
- Discover devices not visible in router settings
- Find repeaters or mesh nodes
- Check common ports (80, 443, 8080)
• Devices are powered off or protected by a firewall.
• The browser is blocking Local Network Access (PNA).
• Incorrect scan range or settings.
To resolve the issue, try to:
1. ↻ Refresh the page and scan again.
2. Check your scan parameters in settings.
3. Use a different browser (we recommend Firefox).
