Slitheris Network Discovery (formerly Network Scanner) is an advanced scanner that will quickly provide you with comprehensive information about your network and so much more.
This scanner goes above and beyond most by really digging deep for information and providing it quickly. It can scan a multitude of devices in a flash and gives you more than just the run-of-the-mill MAC Address. It goes as far as detecting and identifying your OS and device type in addition to using proprietary TCP/UDP OS fingerprinting to detect operating systems like iOS, Android, and Windows with over 80% accuracy.
Slitheris Network Discovery accurately finds pingable devices via standard multi-threaded ping sweeps and detects un-pingable hidden devices using ARP pings and various other advanced discovery technologies. It is even equipped to identify real case-sensitive PC names for Windows computers and servers.
This scanner is suitable for most home users, home offices, and organizations with tiny networks. It also offers a free option for those with more extensive networks.
