ZeroScan | DNS Scanner App for iOS and macOS

Overview

Scanner - All Windows ZeroScan is a network service discovery tool for iOS and macOS. It uses built-in API's to scan your network for devices broadcasting zeroconf (mDNS, DNS-SD, Bonjour) services. This allows you to easily discover the IP addresses of devices on your network, and what ports they are accepting connections on.

Scanner - All Windows ZeroScan was built with the simple goal of easily finding devices on the network without the need to probe IP addresses or constantly refresh a search. It will automatically rescan the network for new devices at a customizable interval. You can customize the scan interval, how long the results stay in your view, and how the results are copied onto your clipboard.

Please note that ZeroScan is not an IP scanner, and it will not actively probe your network. It is listening for network activity and just shows it to you. It is looking for network services such as _ssh._tcp. or _companion-link._tcp. If you find yourself looking for a service that is not coming up, you can have ZeroScan look for it by entering it in the preferences menu. If the device you are looking for is not broadcasting a service like the 40+ that ZeroScan is looking for, it will not be found.

ZeroScan does not collect any data, or send any data out. It only listens for broadcasting services. No information is retained beyond user preferences once the app is closed.

Thanks to Rob de la Cretaz and Remy Porter for testing help.
