SoftPerfect Network Scanner is a free multi-threaded IP, NetBIOS and SNMP scanner with a modern interface and several advanced features. It is intended for both system administrators and general users interested in computer security. The program pings computers, scans for listening TCP ports and displays which types of resources are shared on the network (including system and hidden).

Changelog:

• Added '/config' command-line switch allowing to load a specific XML configuration file on startup.
• Added 'Open as Secure Web (HTTPS)' command.
• Added remote time-of-the-day discovery.
• New live display discovery modes. Either scanning for previously undiscovered nodes only, or rescanning those already discovered, or both (old behaviour).
• Enhanced search dialog (bidirectional now).
• Added IPv6 address discovery (Windows Vista and above).
• Minor code optimisations and GUI enhancements.
