As hosts come online and go offline, there is a constant churn of hosts communicating on a local area network (LAN). Scanning networks with an IP scanner allows IT, network admins, and SecOps professionals to see which IPs are communicating and what types of devices occupy which IP addresses. It also helps to spot rogue, unsanctioned hosts that may be connected to the network. Several network IP scanners are freely available for download and help network administrators and IT admins discover devices on the network and manage IP resources. Let's look at the following tools: Nmap, Advanced IP Scanner, Angry IP Scanner, free IP scanner by Eusing
and the built-in command line and PowerShell.
