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

Changelog:
* Shared resources are no longer automatically exported unless specified explicitly with the /cols switch.
* Added auto-open the most recent file option.
* When launching a third-party application bring up the elevation prompt where necessary.
* Added noncontiguous IP address range scan mode (see help for details).
* Added monitor vendor, model and serial number retrieval.
