How do I find my internal ip address?

I have Ubuntu server 12.04 installed, so I have no GUI. When I do the command ifconfig, I cannot find my internal IP address. It says: inet addr: 127.0.0.1 . Here is the output of ifconfig -a :

eth0 link encap:Ethernet HWaddr 00:06:4f:4a:66:f0 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) eth1 link encap:Ethernet HWaddr 00:16:ec:05:c8:9c BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr 127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:1800 errors:0 dropped:0 overruns:0 frame:0 Tx packets:1800 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:143896 (143.b KB) TX bytes:143896 (143.8 KB) 

# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp 

If someone could edit this for me, the contents of etc/network/interfaces should be on separate lines. The output of host askubuntu.com was:

;; connection timed out; no servers could be reached. 

I set up owncloud and webmin a few months ago and was using them for a month with no problems. I think the power went off one day 2 months ago and I never turned the server back on until yesterday. I haven’t done anything that would have affected the internet setup So i’m not sure why it doesn’t work anymore. As far as my network topology goes, I have a pci-e network card for the pc. The ethernet line goes from the network card to a switch, and then to a modem/router from there.

1. To find your own computer’s IP address, search for the “inet” tag. You’ll find this under “wlo1”. Your private IPv4 address will be displayed just next to where it says “inet”. And you’ll find your IPv6 address next to the “inet6” tag.

Displaying a public IP address in Linux

You can also display your public IP address in Linux. This is the address that’s provided to, for example, websites that you access from your computer. Although it’s possible to determine the address, you should make sure that it’s not disclosed to third parties. If you want to display your public IP address in Linux, follow these steps:

1. Start by opening the terminal by double-clicking the icon or by using the key combination [Ctrl] + [Alt] and [T].
2. Now use the “curl ifconfig.me” command to check your public IP address in Linux. Confirm with the [Enter] key.
3. Your public IP address, which also consists of four blocks of numbers, will show up directly below the command.

More ways to get your IP address in Ubuntu

If you want to find your IP address in Ubuntu you have two alternatives.

Via the terminal

The first alternative involves the “hostname” command. To move ahead with this, just change one step in the process:

1. Open the terminal as described above.
2. Enter the following command: “hostname -I” and confirm with [Enter].
3. Your IP address will be displayed just below the command.

Via the settings

The second way to find your IP address in Ubuntu is through the settings. Here, you can do without the terminal.

1. Click on the cog icon or on “Settings” in the menu bar. This will open your settings.
2. Here, select “Network” in the menu.
3. Just beside your internet connection, click on the arrow pointing to the right or on the cog icon.
4. A window will open that displays the strength of your network’s connection, the connectivity speed, and your IP address.

Displaying your IP address in Debian

In case you want to see your IP address in Debian, you also have some options. Besides a graphical option, you can also use the Network Manager. We’ll show you both.

Via network settings

1. To get your IP address in Debian using the graphical option, click on the network symbol in the top right corner of your desktop.
2. Now select the option “Wired Connected”.
3. Then click on “Wired Settings” to open your network settings.
4. Under “Wired” you’ll see a small cog symbol on the right. Click on it.
5. A host of information about your network will be displayed. Besides the DNS, MAC address and speed, you’ll also find your IPv4 and IPv6 addresses.

Via the command line tool

If you want to get to your IP address via Debian’s Network Manager, you can also use the command line tool “nmcli”.

1. Open the terminal as described above.
2. Enter the following: “nmcli -p device show” and confirm with [Enter].
3. A lot of information will now be displayed. You will find the IP address relatively far down on the right next to “IP4.ADDRESS”.

Как проверить IP адрес в Linux

В создании этой статьи участвовала наша опытная команда редакторов и исследователей, которые проверили ее на точность и полноту.

Команда контент-менеджеров wikiHow тщательно следит за работой редакторов, чтобы гарантировать соответствие каждой статьи нашим высоким стандартам качества.

Из этой статьи вы узнаете, как найти частный и публичный IP-адрес компьютера под управлением Linux.

Поиск частного IP-адреса

Уясните, когда пользоваться данным методом. Если необходимо найти IP-адрес компьютера в беспроводной сети (например, чтобы перенаправить маршрутизатор своего компьютера), вам понадобится частный IP-адрес.

Запустите терминал. Нажмите или дважды щелкните по значку терминала или просто нажмите Ctrl + Alt + T .

Нажмите ↵ Enter . Команда будет выполнена, а на экране отобразятся IP-адреса всех сетевых элементов, включая ваш компьютер.

Найдите строку с IP-адресом компьютера. Обычно это строка с «wlo1» (или «wlan0»), а справа от нее есть тег «inet». [1] X Источник информации

• Адрес IPv6 можно найти рядом с тегом «inet6». Адрес IPv6 не так широко распространен, как адрес IPv4.

Попробуйте ввести команду «hostname». В некоторых версиях Linux, таких как Ubuntu, узнать IP-адрес компьютера можно, если ввести команду hostname -I (это прописная буква «i», а не строчная буква «L») и нажать ↵ Enter .

Поиск публичного IP-адреса

Уясните, когда пользоваться данным методом. Публичный IP-адрес — это адрес, который «видят» веб-сайты и онлайн-сервисы, когда вы открываете их на своем компьютере. Если вы хотите подключиться к своему компьютеру с другого компьютера, который находится в другой сети, вам понадобится публичный IP-адрес.

Запустите терминал. Нажмите или дважды щелкните по значку терминала или просто нажмите Ctrl + Alt + T .

Введите команду отображения публичного IP-адреса. Введите curl ifconfig.me в терминале. Эта команда получит публичный IP-адрес с веб-сайта. [2] X Источник информации

Найдите публичный IP-адрес. IP-адрес, который отобразится под введенной командой, является публичным IP-адресом вашей сети.

How to Find or Check Your IP Address in Linux

An IP address is a codename assigned to a computer on a network. It works as a postal address, ensuring that network traffic is sent to the correct computer.

In this tutorial you will learn how to find your IP address using a Linux operating system.

Find Your IP Address From the Command Line

There are a few different commands you can use to check your IP address. To run these commands, start by opening a terminal window/command line.

Using the hostname Command

One way to check your IP address from the command-line is by using the following command:

The system will display your internal IP address.

Using the ip addr Command

Check your ip address with the ip addr command:

The system will scan your hardware, and display the status for each network adapter you have. Look for an entry that says link/ether. Below it, you should see one of the following:

inet6 fe80::a00:27ff:fe76:1e71/64

The entries will include one for a wired (Ethernet) adapter and a wireless (Wi-Fi) adapter. You may also have an entry for a virtual adapter. Generally, only one entry will have an IP address listed – that is the one you will want.

Note: The number after the slash – /24 and /64 – specifies the size of the network, and it helps with scanning and mapping network size.

Using the ifconfig Command

The third method to find your IP address involves using the ifconfig command. In the command line, enter the following:

The system will display all network connections – including connected, disconnected, and virtual. Look for the one labeled UP, BROADCAST, RUNNING, MULTICAST to find your IP address. This lists both IPv4 and IPv6 addresses.

Note: When you check your IP address, you may notice the term loopback. This refers to an IP address that returns traffic to the same computer. Usually, the loopback address is 127.0.0.1 . If you see that address listed, either you are looking at the wrong line, or you are not connected to the network.

Finding Your IP Address in Linux With a GUI

If you are using a point-and-click interface to run your Linux system, you can check your IP address by following these steps:

1. Go to the Application menu and type Settings into the search bar.

2. Click on the Settings icon that appears among the results, as in the image below:

3. Next, find the Network tab in the Settings Menu and click on the Advanced Wired Settings icon.

4. This opens a new pop-up window with details on wired settings. Here you can find both your IPv4 address and your IPv6 address.

How to Find Public IP Address

To find your public IP address, reach out to an external website.

If you are using a browser, navigate to:

If you are using a command-line or terminal, use a retrieval command like curl or wget to display the external IP address:

wget -O - -q https://checkip.amazonaws.com

Note: Did you know that when you use curl to connect to an insecure website, the output responds with an error? To resolve it, visit our guide on making curl ignore certificates.

What is a Public/Private IP Address?

Each computer in a network is required to have its own IP address. If two systems have the same IP address, it will generate errors on the network. Most modern networks will detect the problem and prompt you to fix it. However, older networks might get confused, trying to route traffic to both computers.

Most systems will have two different IP addresses:

• Private IP address: This is the address used on the network. Also, it is the one you will want to use for configuring routing tools. On smaller networks, the internal IP address typically starts with 192.168.x.x. It is dynamically assigned to your computer whenever you connect.
• Public IP address: This is the IP address that registers on a website when you visit it. When you connect to a small network, your computer connects to a router using an internal IP address. That router, in turn, connects to a bigger network (like an Internet Service Provider), which has its own IP address system.

Note: Learn everything you need to know about public and private IP addresses in our article Public vs. Private IP Address.

Now you know how to find a private and public IP address in Linux using multiple methods.

Each option strikes a balance between speed and complexity. Now you have the flexibility to choose, if you only need your internal IP address, you can use the hostname method. If you need more detailed information, view our article on 31 Linux IP Commands with examples.
