The simplest way to get a quick list of IP addresses and their devices connected to your network is with those OS native commands found in the command line. Commands such as “ipconfig”, “arp -a”, or “ping” allow simple scanning and troubleshooting.

Operating Systems, like Windows and Linux, come with their own native simple networking set of tools. To improve your IP addressing insights, even more, we will show you some tools that allow you to track IP addresses and even manage them. In the end, we will compare some free IPAM tools aka IP address scanning tools that can give you additional information. We will scan a network with native OS commands, find which addresses were assigned dynamically, which statically, and test their connectivity. In this tutorial, you will learn the basic networking skills on how to scan a network for IP addresses.

When you come into the network, the router will look for an available IP address in its pool and assign it to you, so that your device can communicate with others without any conflict.ĭynamic allocation of IP addresses is a great advantage for both end-users and network admins. In a home or small network, the DHCP server is usually a part of the router.

Enter the command ping giving any of the addresses returned by ARP in order to test the response times to that node – don’t include the angle brackets that are shown in that example.Īn automated process in networking, called DHCP (Dynamic Host Configuration Protocol), assigns IP dynamic addresses to hosts as soon as they enter the network.

Enter the command arp -a to get a list of all other IP addresses active on your network.

Note down the subnet mask, the default gateway, and your own computer’s IPv4 address.

On Windows or macOS type ipconfig or on Linux type ifconfig.

Follow these four simple steps to scan your network for IP addresses in use: But to understand how to scan a network, first, you need to understand how are IP addresses assigned.

With 1-2 commands, you can quickly map out the devices in your network and the IP addresses that they are using. Scanning for IP address lets you have better control over your network.
