Linux ipconfig ip address

What is the equivalent terminal command to ipconfig /all?

In windows I can use ipconfig /all and this displays all the info about my connection. In terminal using ifconfig does not and only supplies limited info. I can use network manager, but it would be useful to know the command line alternative. So my question is: what is the command line to supply ip address, gateway, subnet mask, DNS the same way ipconfig /all supplies in Windows. Thanks all

The only thing missing from ifconfig are the gateway and DNS servers.

15.04 and newer

To get the DNS and Gateway info just type:

The output lists some device parameters including some IP4.DNS[x] entries, which show the DNS servers and a IP4.ADDRESS[1] line which lists the IP and Gateway used (look for the gw = . part at the end of the line up to 15.10). On 16.04 and newer versions there is a IP4.GATEWAY line which is pretty self explanatory.

Replace eth0 with the actual device name you’re using, which may not be the same. To get a list of devices and their status type:

Up to and including 14.10

You can get these with nm-tool (in Ubuntu versions prior to 15.04) which BTW is the command line version of network manager.

To run it just type in a terminal:

If you’re using Ubuntu 15.04 or newer the nm-tool has been replaced by the nmcli command which is different. Check the section called «15.04 and newer» above this one in this case.

@Enkouyami I’m using 0.9.10 and it works just fine. Not sure if this particular command is a new addition or not, but you can try to get help by using nmcli dev help to see which commands are available.

This does not work on Linux Mint 17 based on Ubuntu 14.04. The command to use is nmcli d list which shows info for all connections, connected or not.

ipconfig shows things like hostname, DNS servers, those are in a different place than just IP addresses in linux, so you will need a couple of commands.

hostname ifconfig -a cat /etc/resolv.conf 

That shows what I want to see 99% of the time, but ipconfig /all also shows things like DHCP lease times and servers.

cat /var/lib/dhcp/dhclient.leases 

Was looking at few links and finally found the below working:

IP4.ADDRESS[1]: ip = 195.168.0.107/24, gw = 192.168.0.1 IP4.DNS[1]: 192.168.0.1 IP4.DOMAIN[1]: local 

Also all the network related details can be found using putting simply:

nmcli dev list | grep IP4 means take the output of nmcli dev list and then feed it (using the pipe | ) into grep and keep lines that contain regex pattern IP4 .

Here’s the simplest equivalent i could find for ubuntu 17.04

Sample output (ip4 stuff only):

nmcli device show | grep IP4 IP4.ADDRESS[1]: 172.27.35.55/24 IP4.GATEWAY: 172.27.35.1 IP4.ROUTE[1]: dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000 IP4.DNS[1]: 172.27.35.1 IP4.ADDRESS[1]: 127.0.0.1/8 IP4.GATEWAY: 

I needed to work out what DHCP server I was connected to via Ubuntu 14.04 so I used this command:

as this is what I wanted only from the original command «nmcli dev list»

DHCP4.OPTION[1]: expiry = 1464073312 DHCP4.OPTION[2]: domain_name = [omitted_proper_details] DHCP4.OPTION[3]: broadcast_address = 10.1.45.255 DHCP4.OPTION[4]: dhcp_message_type = 5 DHCP4.OPTION[5]: dhcp_lease_time = 432000 DHCP4.OPTION[6]: ip_address = 10.1.45.132 DHCP4.OPTION[7]: subnet_mask = 255.255.255.0 DHCP4.OPTION[8]: dhcp_renewal_time = 216000 DHCP4.OPTION[9]: routers = 10.1.45.1 DHCP4.OPTION[10]: domain_name_servers = 10.1.26.10 10.1.20.10 DHCP4.OPTION[11]: dhcp_rebinding_time = 378000 DHCP4.OPTION[12]: network_number = 10.1.45.0 DHCP4.OPTION[13]: dhcp_server_identifier = 10.1.20.10 

Gives me all the DCHP/DNS details I need, just like ipconfig /all

How to Find Your IP Address in Linux

Many times it happens that you feel the need to know the IP address of your device. Internet Protocol address or IP address is a set of numeric digits that are needed to identify your device and enable network communication because all the devices that are connected through a network know each other only through their IP addresses. Moreover, the IP address also specifies the location of a device. So it becomes necessary for you at times to know what is the IP address of whichever device you are using. Now how to find this IP address is the real question. In the article below, we will tell you all the ways through which you can find the IP address of your device while working in a Linux environment, in our case, Ubuntu 22.04. The same commands will work on the new Ubuntu 22.04 version too.

This tutorial will show you how to check your IP address on Linux systems like Ubuntu, Linux Mint and Debian using the command line. I will also explain the differences between private and public IP addresses, discuss the various network interfaces, and explain the ip route command and its role in network address translation.

The first step is to understand the two types of IP addresses: private and public. Private IP addresses are used within a local network or internet connection and cannot be reached from outside of that connection. Public IP addresses, however, can be accessed from anywhere in the world.

If you’re using an Ubuntu system, you can get your personal IP address by using this command: ifconfig . This will list all of your active network interfaces along with their associated private or public IP addresses.

Another way to get your public/private IPs is by entering ip route in the terminal window. This command shows all currently active routes along with their corresponding source/destination networks. You can then use these routes to trace out which devices are connected to your computer’s network interfaces – this includes public/private IPs allocated by DHCP servers such as routers.

Finally, if you’re connected to a router via an ethernet cable or Wi-Fi (wireless) connection, then it’s likely that Network Address Translation (NAT) is being used – this means that requests sent from one machine inside the same local area network are being translated so that they appear as if they came from one single device with a single IPS address when viewed from outside of the LAN. To check if NAT is enabled in your current setup, use tracroute followed by any website domain name (e.g., google.com). The result should show whether or not packets are routed through NAT before reaching their destination web server – if so then NAT is enabled and working correctly!

Four ways to find your current IP Address in Linux

Following are the four methods through which you can find the IP address of your device:

Method # 1: On the Desktop

The first method of finding the IP address of your device is through the Linux desktop interface. For this, you need to proceed as follows:

Click on your network connection icon (Wi-Fi icon) at the top right of the title bar on which Ubuntu Desktop is written. A cascading menu will appear, which is shown below:

From the menu shown above, click on Connection Information. A new Connection Information window will appear, which is shown below:

In the window shown above, the red highlighted rectangle shows the IP address of your device written in front of IP Address field.

Method #2: On the Shell with ip command

The second method of finding the IP address of your device is through a terminal command. To do this, you need to perform the following steps:

First, open the terminal by pressing Ctrl+ T or you can click on the terminal icon directly if it is shown on your taskbar. You can also click on the search icon located on the taskbar and then type Terminal and press enter to open it. The newly opened terminal window is shown below:

Type the command ip addr show in the terminal and press enter.

This command is shown below:

As soon as you press enter, some information will be displayed on the terminal window. From the information shown below in the terminal screen, the highlighted rectangle shows the IP address of your device besides the inet field.

Method # 3: On the Shell with ifconfig command

The third method of finding the IP address of your device is through another terminal command. For this, you need to follow the steps mentioned below:

Launch the terminal by pressing Ctrl+ T or clicking on the terminal icon, or searching for terminal in the search window shown below and pressing enter.

in the newly opened terminal window and press enter.

As soon as you press enter, a lot of information will be displayed on the terminal screen. From the displayed information below, the highlighted rectangle shows the IP address of your device beside the field of inet addr.

The ifconfig command works in the same way for finding the IP address of a device using terminal in Linux as ipconfig command works for finding the IP address of a device using command prompt in Windows.

Method # 4: On the Shell by using the hostname command

Method four for finding the IP address of your device makes use of yet another terminal command. For this method, you need to follow the following steps:

Launch the terminal by pressing Ctrl+ T or clicking on the terminal icon located on the taskbar or search for terminal in the search window and press enter.

When the terminal window appears, type the command:

and press enter. This command is shown in the following window:

As soon as you will press enter, the IP address of your device will be displayed on the terminal right below your entered command. This is shown below:

Conclusion

By using any of the methods listed above, you can find the IP address of your device very quickly and enable a very safe and secure network communication through it. IP address gives an identity to your device so that you can recognize it whenever you want to. Once you know the IP address of your device, you are free to interact with any other device that is connected to the same network to which you are connected. I hope that this article will help you a lot in the future.
