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.
How to scan the LAN for IP addresses
1. IP Config Method
- Type Cmd in the Start menu search bar.
- Type ipconfig.
- Ping this machine IP address by punching in the following command ping 192.168.x.xxx
- In the next step type arp -a.
2. Use PRTG Network Monitor
One alternative way that can help you keep track of your entire LAN and WAN is by using a dedicated tool, such as PRTG Network Monitor.
You can monitor the bandwidth, all your workstations, routers, and servers as well.
The tool is able to scan network segments by pinging defined IP ranges and this way PRTG will recognize a broad range of devices and systems in an automatic manner, and it will create sensors from predefined device templates.
PRTG Network Monitor also allows you to create maps and web pages with up-to-date monitoring data.
