Finding Your Router’s IP Address (Default Gateway) in Ubuntu and Other Linux
|
||||||
|
======
|
||||||
|
You probably already know how to get your system’s IP address in Linux.
|
||||||
|
|
||||||
|
But how do you know the IP address of your router?
|
||||||
|
|
||||||
|
I am not talking about the public-facing IP which you can get by connecting to websites like [Show My IP][1] or simply [searching for ‘what is my ip’][2] in [DuckDuckGo][3].
|
||||||
|
|
||||||
|
I am talking about the default gateway IP which your Linux desktop uses to connect to it.
|
||||||
|
|
||||||
|
Why do you need it? Well, if you need to change the SSID, password, or other configuration of your wi-fi/network, you have to connect to it. And the simples way is to type the IP address of the router in a web browser and then use the router’s username and password.
|
||||||
|
|
||||||
|
While I cannot help you with the username and password of your router, I can surely tell you how to get its IP.
|
||||||
|
|
||||||
|
As always, I’ll show both GUI and command-line methods.
|
||||||
|
|
||||||
|
### Method 1: Get the router’s IP address in Linux using GUI
|
||||||
|
|
||||||
|
It’s quite simple actually. I am using GNOME desktop with Ubuntu here. If you use some [other desktop environments][4], screenshots may look different.
|
||||||
|
|
||||||
|
Open System Settings:
|
||||||
|
|
||||||
|
![go to settings][5]
|
||||||
|
|
||||||
|
Now go to Wi-Fi or Network (if you are using a wired, Ethernet connection). Here, click on the little settings symbol beside your currently used network.
|
||||||
|
|
||||||
|
![access network settings ubuntu][6]
|
||||||
|
|
||||||
|
It will open a new window with several details about your connection such as the IP address, DNS, and [Mac address][7]. You can also see the [saved wifi password][8] under the security tab.
|
||||||
|
|
||||||
|
You’ll also see an entry named ‘Default Route’. This is what you are looking for. The IP address of your router.
|
||||||
|
|
||||||
|
![defaul gateway ip ubuntu][9]
|
||||||
|
|
||||||
|
Your system and all other devices on your network connect to the router using this IP address. This is the setup most households have.
|
||||||
|
|
||||||
|
Now that I have shown the GUI method, let’s go to the terminal route.
|
||||||
|
|
||||||
|
### Method 2: Get the router’s IP address in Linux command line
|
||||||
|
|
||||||
|
Open a terminal and use the following command:
|
||||||
|
|
||||||
|
```
|
||||||
|
ip route
|
||||||
|
```
|
||||||
|
|
||||||
|
It will show you a few entries.
|
||||||
|
|
||||||
|
```
|
||||||
|
[email protected]:~$ ip route
|
||||||
|
default via 192.168.1.1 dev wlp0s20f3 proto dhcp metric 600
|
||||||
|
169.254.0.0/16 dev wlp0s20f3 scope link metric 1000
|
||||||
|
192.168.1.0/24 dev wlp0s20f3 proto kernel scope link src 192.168.1.34 metric 600
|
||||||
|
```
|
||||||
|
|
||||||
|
The first line, which starts with ‘default via’, gives you the gateway IP. This is your router’s IP address.
|
||||||
|
|
||||||
|
![defaul route linux terminal][10]
|
||||||
|
|
||||||
|
As you can see, 192.168.1.1 is the IP address of my router. Usually, the router’s IP address is the first number of the subnet. However, this is not a hard and fast rule. I have seen routers with x.y.z.30 addresses as well.
|
||||||
|
|
||||||
|
### Bonus tip
|
||||||
|
|
||||||
|
As shared by Samir in the comments, you can also use the ping command to get the gateway IP:
|
||||||
|
|
||||||
|
```
|
||||||
|
ping _gateway
|
||||||
|
```
|
||||||
|
|
||||||
|
![ping gateway][11]
|
||||||
|
|
||||||
|
In case you didn’t know, you have to [use the Ctrl+C to stop a running command in Linux][12].
|
||||||
|
|
||||||
|
I hope you find this tip useful when you need it.
