# How to Configuring IP Addresses in the /etc/network/interfaces on Debian

Here I will provide an example of IP Address configuration in /etc/network/interfaces which is usually found in Debian, older versions of Ubuntu, and older versions of Linux Mint. I will make an example for Static IP Address and DHCP

## A. Static

First go to `sudo nano /etc/network/interfaces` .  
For example here I want to configure the IP Address with IP 192.168.2.236 on interface enp0s5.

`auto enp0s5`  
`iface enp0s5 inet static`  
`address 192.168.2.236/24`  
`gateway 192.168.2.254`  
`dns-nameservers 192.168.2.254 1.1.1.1 8.8.8.8`

Here I will give an explanation of the parameters above.

| **<mark>COMMAND</mark>** | **<mark>EXPLANATION</mark>** |
| --- | --- |
| `auto enp0s5` | Indicates that the enp0s5 network interface should be automatically enabled when booting. This ensures that the network connection will be initialized without manual intervention. |
| `iface enp0s5 inet static` | Indicates that this is the configuration for interface enp0s5 for IPv4 with static mode |
| `address 192.168.2.236/24` | Useful for IP Address allocation with prefix /24 (255.255.255.0). |
| `gateway 192.168.2.254` | Useful for IP Gateway allocation |
| `dns-nameservers 192.168.2.254 1.1.1.1 8.8.8.8` | Specifies the DNS Server IP to access the domain name. |

After everything has been configured, save the file and restart the service network to save the changes, here is the command:

* If using systemd, `sudo systemctl restart networking`
    
* If using sysinit, `sudo service networking restart`
    

## B. DHCP

For DHCP itself, it is very simple.

`auto enp0s5`  
`iface enp0s5 inet dhcp`

Yes it is like that, after configuring, restart the network service that I have written above
