Scanning the LAN for IP addresses is extremely important, especially if you are an admin and want to analyze all the devices connected to the network.

Admins usually prefer to have access to shared folders and the control to automatically shut down the PC, remotely.

IP addresses are part of layer 3 in the OSI network and are necessary for Inter-VLAN communication. In essence, every layer 3 device will be needing an IP address.

The IP address is also required if you are configuring DHCP snooping and some of the other advanced features.

There is more than one way to scan the LAN for IP addresses and in this segment, we will walk you through some of the best means to do so.
