NetScan: a network scanner utility
- Detects the local IPv4 networks of all active network interfaces (ignores loopback, inactive interfaces, IPv6 and Link-local/APIPA 169.254.x.x)
- Scan multiple IP ranges at once (one range per line)
- Save/Load IP ranges as presets
- Display online/offline status of every IP
- Display/hide Hostname
- Display/hide MAC Address
- Display/hide Vendor (offline lookup, IEEE OUI table)
- Display TTL and the probable device OS
- Hide offline IP's
- Pause/Stop scanning (on pause current threads continue and no new ones will start)
See the User's Guide for downloads, runtimes, installation and usage.
