#FING NETWORK SCANNER DEFINITION MAC#
Not only is device identification severely compromised (the first half of the MAC Address was the primary means of identifying manufacturer), but recognising the same device on repeat scans is highly unreliable. For an app like Fing this is pretty crippling. IOS11 Update: With the latest iOS update, apps are no longer permitted to access MAC Address information from network devices. Whether this applies to the network data collected, or just account details is not clear. Fing's privacy policy has the usual assurance of complying with relevant privacy law, but does give them the out to share information with business partners. hile it could tell someone what you have, which has the potential for advertising if you have any devices with known vulnerabilities, it doesn't specifically create any additional exposure in itself. You may (quite reasonably) have issues with sending your network contents to a third party. You can set Fing to notify you on state change for each device, so critical devices can be actively monitore (your smart home hub of choice, or security devices for example). Of course, the device details page lists all the pertinent info about it's network settings, IP, MAC address, OS, any NetBIOS or Bonjour IDs detected, if it's hosting a file share, and so forth.Īdditionally, you can flag devices as 'Critical' or 'Favorite' and they will be so marked in the device list. You can ping the device to test it's connection stability, and do a port scan to check for vulnerable open ports. This can help track things down, but also acts as a diagnostic of potential issues on the network. Second, Fing will keep track of the history of devices over time, and can keep an event log of when things were first noticed and when it saw them go on or offline. Once you've identified a device, you can optionally name it (and select a handy icon from a large library), and give it a location to help you keep track. It does a pretty good job and greatly helps in thinning out the list that you need to track down further. However, the execution is slick and offers some nice additions to assist in keeping track of the growing list of devices in our homes.įirstly, for each device it detects, it will attempt to identify the device based on some known identifiers. Fing itself offers network scanning of the local subnet, device port scanning, and connectivity testing to local or remote addresses. Fing is billed as a 'super-fast network scanner', and that's pretty much what it does, at least originally.
