In this tutorial you volition acquire how to find your IP accost using a Linux operating system.

• Access to a terminal window/command-line (optional) (Ctrl–Alt–T, Ctrl–Alt–F2)

Detect Your IP Address From the Command Line

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

Using the hostname Control

          hostname -I        

The organisation volition display your internal IP address.

Check your ip accost with the ip addr command:

          ip addr        

The system will scan your hardware, and brandish the condition for each network adapter you have. Expect for an entry that says link/ether. Below it, you should see ane of the following:

          inet 192.168.0.10/24        

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

The entries will include ane for a wired (Ethernet) adapter and a wireless (Wi-Fi) adapter. You may as well accept an entry for a virtual adapter. Generally, just one entry will take 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 3rd method to find your IP address involves using the ifconfig command. In the command line, enter the following:

          ifconfig        

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

Annotation: When you check your IP address, you may find the term loopback. This refers to an IP address that returns traffic to the same computer. Usually, the loopback address is 127.0.0.ane .

Note: Did you know that when you lot use roll to connect to an insecure website, the output responds with an mistake? 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 accept its own IP address. If two systems take the same IP address, it will generate errors on the network. Nigh modernistic networks will detect the trouble and prompt you to gear up it. However, older networks might get confused, trying to road traffic to both computers.

Near 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 accost typically starts with 192.168.x.10. It is dynamically assigned to your estimator whenever yous connect.
• Public IP accost: This is the IP accost that registers on a website when you visit it. When y'all connect to a small network, your reckoner 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.

Conclusion

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

Each choice strikes a balance between speed and complication. Now yous accept the flexibility to choose, if y'all merely need your internal IP address, you can use the hostname method. If you demand more detailed information, view our commodity on 31 Linux IP Commands with examples.
