This means any changes to it can be overwritten at random making editing the “ nf” file an unreliable solution. The reason for this is because Raspbian comes with a program called resolvconf, this file dynamically generates the nf file. While in some setups you can modify the /etc/nf file you shouldn’t do this on Raspbian installations. It just requires modifying one file, in this case, its the dhcpcd configuration file. Changing your DNS servers is a straightforward process on the Raspberry Pi. If you have any problems, please let us know in the comments at the bottom of this page.ġ. We recommend that you do this tutorial on the latest version of Raspbian to ensure that everything will work correctly. ![]() Setting the DNS Servers on your Raspberry Pi You will need the following equipment for this guide on setting the DNS server on the Raspberry Pi. This tutorial simply goes into the steps of changing the way your Pi resolves domain names. If you’re looking to set up a dynamic DNS for accessing your Raspberry Pi then our tutorial on port forwarding and setting up Dynamic DNS will help you out. Alternatives like Cloudflare 1.1.1.1 offer increased privacy by not logging any identifiable data and offering HTTPS over DNS. There is also the privacy factor to be considered, typically your ISP’s DNS server will leak your IP address as well as cache details about what websites you are visiting. Many ISP provided DNS servers can be incredibly slow at lookups and sometimes can take ages to update and add domains. One of the top reasons being performance. There are many reasons why you might want to utilize a different DNS server to your ISP’s default. In addition to showing you what file you will need to edit, we will also walk you through a couple of methods of ensuring your Raspberry Pi is using your newly set DNS. ![]() See our Avast! article for a resolution.The process of changing the DNS server on your Raspberry Pi is a pretty simple process and involves modifying a single file. Avast! Antivirus 2015+: A new "Secure DNS" auto-configuration was added that overrides OpenDNS.Comcast/XFinity Constant Guard: See our Constant Guard Guide for more details on how to resolve.Resolution 4: There are several causes of this: Potential Cause 4: There is software on your computer interfering with the OpenDNS setup that changes the DNS settings on your computer. We'd recommend disabling IPv6 altogether or setting it to Local Link Only on a Mac OSX machine by following the instructions on our disabling IPv6 guide here. Resolution 3: Please ensure that if IPv6 is enabled (not recommended) that the only IPv6 DNS server is set to your router. Potential Cause 3: IPv6 (Internet Protocol Version 6) is enabled on your computer, and you have IPv6 DNS settings configured on your computer. Resolution 2: Please refer the following links for a VPN client or the Roaming Client/DNSCrypt. Potential Cause 2: You are utilizing a VPN client or the Roaming Client/DNSCrypt and your IP address changes away from OpenDNS on its own. Local DNS resolution Resolution Router providing incorrect DHCP DNS servers If you're experiencing difficulties, you may also configure directly for OpenDNS by entering in 208.67.220.220 and 208.67.222.222 using the "+" button. įor Mac OSX, be sure to remove the existing DNS entries (under Network Preferences -> Advanced -> DNS) and use the "-" button to remove the existing DNS servers. On Windows, check your configuration using the Windows configuration instructions, but rather than enter the OpenDNS numbers, ensure that they are set to "Obtain DNS server address automatically". Resolution 1: Check the configuration on your computer to ensure that different DNS server settings are not configured. Potential Cause 1: Your computer is directly configured for another DNS Server, and therefore is bypassing the OpenDNS settings on your router. To confirm if your device(s) are configured for OpenDNS, please visit and look for the check mark. In this scenario, you have configured OpenDNS on your router, and it works for most of the computers, tablets, and WiFi-Connected iOS and Android devices on your network, but it doesn't work on one computer. ![]()
