Nmap scan report for androidb23f67te05e1c8 As you can see that there are three devices connected to my network. The router itself, my laptop and my Galaxy S2.

If you are wondering about why I used 24 in the above command, you should know a little about CIDR notation. It basically means that the scanning will be from When I first wrote this article, there was no GUI tool for this task. I suggested including a periodic device scan feature in this tool and the developer readily agreed. So, now we have a GUI tool that does this task.

Just run install this app and run it. It will periodically scan for new devices on the network and will notify you if there is a new device. This application is only available for elementary OS, Ubuntu and hopefully, other Ubuntu based Linux distributions. You can find installation instructions on this detailed article on Nutty. Oh, you can also log in to your router and see the devices connected to your devices.

I let you figure the best way to find devices connected to your network. I am an avid Linux lover and open source enthusiast. I use Ubuntu and believe in sharing knowledge. Apart from Linux, I love classic detective mysteries. I'm a huge fan of Agatha Christie's work. Please log in again. The login page will open in a new tab.

Use the following command to install nmap in Ubuntu based Linux distributions: sudo apt-get install nmap You can easily install it in other Linux distributions as well.

In the ARP results shown above, you can see four addresses that are labeled dynamic and six addresses that are categorized as static. If you have not made any intervention at all to allocate addresses manually to devices on your network, then all of the physical pieces of equipment will have dynamic addresses. The static addresses are used for administration by your router. The first address in the list is the address of your router.

This should match the Default Gateway address that you saw in the ipconfig results.

In the illustrations in this section, you can see that the ipconfig and arp commands have revealed the address of the router, the address of the computer from which the commands were issued, and the network addresses of four more devices that are connected to the network. Keeping track of the address allocations on your network is very important.

You can choose two ways to allocate IP addresses. In one method, which is the static IP address , you enter an address into the network settings of each device. As you perform this task, you need to keep a central record of those address allocations and be careful not to repeat addresses. The second method that you can use to allocate addresses is the dynamic IP address system. This scenario is now widely used by network administrators. In this scenario, each device, when connecting to the network has to contact a central server and request an address.

DHCP IP reservation

This server operates the DHCP system. Under DHCP no device is allocated an address permanently. The dynamic addressing method requires a lot more equipment than the static address allocation method. However, it is easier to automate than the static address method. If you have a small network, you could easily operate a static method. However, the automation that is available with the DHCP system makes it more attractive to the administrators of large networks.

Networks use hostnames as well as IP addresses to identify devices. Under the dynamic address system, the hostname stays the same, but the IP address associated with it will change frequently. Because of address changes, it is necessary to automate the mapping between the host names and IP address that are held in your networks Domain Name Server. So, dynamic addressing requires automation tools.

On the other hand, having to manually assign an address for each computer, mobile device and printer connected to the network can become very time consuming for administrators of large networks. As a small network grows, the recording of IP address allocations needs to be very strictly controlled. Any slip-ups in the listing of assigned addresses can result in networking disasters.

So, you are going to need tools to help monitor IP address allocation even in small networks. The IP Address Manager is needed in order to check on the addresses that are currently live on the network and match the current status up to the records in the DHCP server.

Find the IP Address of Computers on Your Home Network the Easy Way

An IP address scanner is just going to give you more or less the same information that you got from the arp command. There are a few IP address scanner tools that can add on a little extra information and present them in a more attractive format. A good scanner tool should also allow you to save results to a file so you can compare IP address usage over time or reconcile address usage with your DNS server and DHCP server if you get to the point where these functions are managed away from the router.

Most IP address scanners just add a front end to that arp command you tried yourself. An alternative method uses a utility called Ping and runs the command repeatedly to see which addresses respond. This category of software is called a Ping sweep tool. If a tool just sweeps the network and lists current addresses, strictly speaking, that is an address scanner. If you have a small network with static IP addresses, then a list of IP addresses currently in use on the network may be all the address tracking you need.

How to scan local network for IP addresses - includes tools | Comparitech

The basic task of scanning for the addresses currently in use is a necessary network management responsibility because it enables you to check for unauthorized connections. However, just to be sure, periodic scans of the network should be performed. If you operate a system that allows anyone to connect, such as a BYOD wifi router for the private use of employees, then it is advisable to check on the addresses of the devices connected to the network and keep a log of them. To give you an idea of the type of information you can get from an IP address scanner or a Ping sweep tool, take a look at these two tools:.

The output of a scan shows the IP Address of each device on the network , together with the hostname and the contact response time. To get a look at how a Ping sweep tool operates you could try out the SolarWinds Ping Sweep function.
