That's not what we're going to do.
Instead, we'll issue the command like so:. The output of the command will display IP addresses as well as the associated ethernet device Figure A.
The only caveat, is that unless you know the MAC address of every device on your network , you won't have a clue as to which machine the IP addresses are assigned. Even without knowing what machine is associated with what address you at least know what addresses are being used. Next, we use a command that offers more options.
Said command is nmap. You won't find nmap installed on your Linux machine by default, so we must add it to the system. Open a terminal window or log into your GUI-less server and issue the command:.
Once the installation completes, you are ready to scan your LAN with nmap. To find out what addresses are in use, issue the command:. Let's make nmap more useful. Because it offers a bit more flexibility, we can also discover what operating system is associated with an IP address. The command for this is:. Depending on the size of your network, this command can take some time. And if your network is large, consider sending the output of the command to a file like so:.
You can then view the file with a text editor to find out what operating system is attached to an IP address Figure C.

Our award-winning customer care team is here for you. An IP address serves both the purpose of identification and localisation of a machine. The IP address is unique within the network, allowing the communication between all connected devices. You should also know that there are two types of IP addresses : public and private.
The public IP address is the address used to communicate over the Internet, the same way your physical address is used for postal mail. However, in the context of a local network such as a home where are router is used , each device is assigned a private IP address unique within this sub-network. This is used inside this local network, without directly exposing the public IP which is used by the router to communicate with the Internet.
Another distinction can be made between IPv4 and IPv6 protocol.
IPv4 is the classic IP format,consisting of a basic 4 part structure, with four bytes separated by dots e. However, with the growing number of devices, IPv4 will soon be unable to offer enough addresses. This is why IPv6 was invented, a format using bit addresses compared to the bit addresses used by IPv4. The fastest and the simplest way to check your IP address is by using the ip command.
You can use this command in the following fashion:. Actually, you can further shorten this command to just ip a. It will give you the exact same result. There are some other ways to check IP address in Linux but these two commands are more than enough to serve the purpose.
