Network IP Scanner Toolbox

NetScanner finds the devices on your Wi-Fi and shows you at a glance what is going on in your network – now with history, widgets and Siri.

FIND DEVICES • Finds active devices on the local network, including those that do not answer ping • Shows IP address, hostname, manufacturer, model, MAC address (where available) and response time • Checks the common ports on request (SSH, HTTP/HTTPS, SMB, RDP, printers and more) • Opens a device's web interface with one tap • Lists all services on your network (AirPlay, printers, file shares) in the Bonjour browser

HISTORY AND MY DEVICES • Remembers your scans and shows which devices are new and which are gone • Lets you give devices your own names and notes and keeps a "My Devices" list • Pins important scans with a title and a note • Exports reports as CSV, PDF or JSON

TOOLS • Ping with statistics, DNS lookup and traceroute – also over IPv6 • Port check for single devices with your own port lists and service banners • Web check: TLS certificate with issuer and validity, HTTP headers and redirects • Mail check: MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT and BIMI of a domain, with an explanation for every result • Speed test for download, upload and latency, with history and a chart by connection type • Subnet calculator with subnet splitting and planning for growth • Public IP address with provider • Wi-Fi connection quality to your router in real time

WIDGETS, CONTROLS AND SIRI • Network widget with public IP (refresh with a tap), last scan and last speed test • Dedicated speed test widget: start a measurement right in the widget • Control Center controls (iOS 18): start a scan or a speed test with one tap • Siri and Shortcuts: scan, ping, speed test, traceroute and more by voice or automation

FOR FRITZ!BOX USERS On request, NetScanner reads the device list directly from your FRITZ!Box. This also shows devices that otherwise barely appear in the network, with names and MAC addresses.

PRIVACY • No account, no ads, no tracking • All scan results, names and notes stay on your device • Router credentials are stored in the keychain and only sent to your own router

GOOD TO KNOW • NetScanner needs the "Local Network" permission, otherwise the scan finds nothing. • iOS does not give apps the MAC addresses of other devices. NetScanner determines them from Bonjour, UPnP and NetBIOS or from the FRITZ!Box list. For devices with a random ("private") Wi-Fi address, the manufacturer is therefore unknown. • Devices in deep sleep (for example battery-powered door locks) do not answer and cannot appear. • The public IP address (also in the widget) is looked up via ipify.org. Depending on your connection, a speed test transfers several hundred megabytes. It uses the open measurement service of Measurement Lab, which publishes the results including the IP address as open data. • Use port checks and scans only on your own networks.
