Find ip by mac address command
In order to get a list of the IP addresses of all of the devices connected to your network. Follow these steps:. This will give you a bare list of IP addresses , but then you will need to utilize other tools in order to investigate further or troubleshoot network problems. We get into a lot of detail below. If you only have time for a quick glance, here is our list of the best IP address scanner and tracker tools:. In this guide, you will learn about a quick way to find out the IP addresses on your network, and then you will read about some basic tools that will get that information in a more digestible format and give you options to manage addresses.

The ipconfig command will return a set of results for each of the network adapters that you have set up on your computer. Those adapters that are not active will show the result, Media disconnected , so you can ignore those. You now have the addresses of two devices on your network. The IPv4 address is the network address of the computer that you are using, and the default gateway result is the IP address of your router. The list of IP addresses that you see below that shows all of the other addresses that have been allocated on your network.
So the complete list is all of these addresses including the address of your computer. 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.
How to find IP and MAC Address by command line in Linux
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.
How to Use an IP Address to Find a MAC Address
In this scenario, each device, when connecting to the network has to contact a central server and request an address. 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. To masquerade spoof the identity of a different device. MAC addressing spoofing can be used legitimately to register a home network gateway device with an internet provider. It can also have malicious intent, such as to defeat the MAC address filtering feature to break into the network.
I'm an avid Linux lover and enjoy hands-on with new promising distros. Currently, I'm using Ubuntu as a daily driver and run several other distros such as Fedora, Solus, Manjaro, Debian, and some new ones on my test PC and virtual machines. I have a day job as an Engineer, and this website is one of my favorite past time activities especially during Winter ;. Hope you enjoy using this website as much as I do writing for it.
