The IP addresses that are used for communication within the local area network (LAN) are referred to as private IP addresses. 

For configuring your network devices and enabling sound communication between them, you might need to know the private IP addresses of these devices. 

Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform Debian related queries.

In this context, we shall look into methods of finding out the private IP addresses of your Debian 10 system.

Ways to find your Private IP Address in Debian 10?

There are different methods of viewing your private IP address in Debian 10. 

Here, we are going to discuss all of these methods below.

1. The "ip" command with the "a" Flag Method:

The "ip" command with the "a" flag can be used to find out the private IP address of a Linux based device. The "a" flag basically refers to "address". 

We can use this command as follows:

ip a

2. The "net-tools" Utility Method:

We can even use the "net-tools" utility in our Debian 10 system to view its private IP address. 

Basically, there is a specific command within this utility that can be used to serve the said purpose. 

First, we need to install the net-tools utility by running the following command:

sudo apt install net-tools

After successfully installing this utility, you have to run the following command:

/sbin/ifconfig

In the output of this command, you will see the private IP address of our Debian 10 system.

3. The "hostname" with the "-I" Flag Method:

The "hostname" command with the "-I" flag can also be used to find out the private IP address of a Linux based device. 

We can use this command in the following manner:

hostname –I

This command will display the private IP address of the Debian 10 system.

4. The "nmcli" Command Method:

The "nmcli" command along with the "-p" flag can be considered as another method of viewing the IP address of our Debian 10 system. 

We can run this command in the following manner:

nmcli –p device show

This command will display the private IP address of the Debian 10 system.

5. The "ip" command with the "r" Flag Method:

The "ip" command with the "r" flag can be used to find out the private IP address of a Linux based device. 

The "r" flag basically refers to "route". 

We can use this command as follows:

ip r

This command will display the private IP address of the Debian 10 system. 

6. The GUI based Method:

There are some users who do not prefer to use the Debian 10 terminal rather they are more comfortable with its GUI. 

This method facilitates all such users. 

i. To use this method for finding out the private IP address of our Debian 10 system, we will first click on the network icon located on the Debian 10 taskbar.

ii. Now we need to select the Wired Connected option from the menu that appears.

iii. After that, we have to click on the Wired Settings option.
