# Linux DNS Setup

#### Static IP address

1\. Navigate to the SafeDNS **Dashboard > Settings** and copy your IP address in the "**Enter an IP address or DynDNS**" box. Click "**Add**".

2\. Change your system’s DNS servers to SafeDNS addresses - **195.46.39.39** and **195.46.39.40**

If you configure the network through NetworkManager, it will be sufficient to add SafeDNS servers there.

Open the settings of the current Network Interface.

Add SafeDNS servers: **195.46.39.39** and **195.46.39.40**.

Otherwise, you need to find out which application is used for the network settings and add SafeDNS servers there.

**Your Linux device is now filtered with the SafeDNS filtering policy.**

#### Dynamic IP address

1\. Install and configure **ddclient**.

**ddclient** package is shipped with most Linux distributions.

If your Linux distribution doesn’t have ddclient, you can download it from [GitHub](https://github.com/ddclient/ddclient).

After ddclient is installed, you need to insert the next configuration in its config file (/etc/ddclient.conf or /etc/ddclient/ddclient.conf):

<p class="callout info">daemon=300  
syslog=yes  
ssl=yes  
  
protocol=dyndns2  
server=www.safedns.com  
  
use=web  
web=http://www.safedns.com/nic/myip  
  
\# Replace with your email and password for www.safedns.com  
login=you@yourmail.com  
password=your\_password  
  
\# Enter any name for your device.  
\# If you have several computers with dynamic IPs their names must differ.  
laptop</p>

Reboot your device and start ddclient.

If the similar string is shown in the system logs (/var/log/syslog, /var/log/daemon.log or /var/log/messages), ddclient is successfully configured:

<p class="callout info">Aug 14 12:49:13 laptop ddclient\[4105\]: SUCCESS: updating laptop: good: IP address set to 18.26.28.10</p>

2\. Change your system’s DNS servers to SafeDNS addresses - **195.46.39.39** and **195.46.39.40**

If you configure the network through NetworkManager, it will be sufficient to add SafeDNS servers there.

Open the settings of the current Network Interface.
