![]() “”) into their browser, DNS lookup is triggered. How does DNS actually work?Īfter a user types a domain name (e.g. In this section, we will learn how does DNS work, what is the difference between recursive and iterative DNS resolver, how does unbound work and what are the pros and the cons of running your own recursive DNS resolver at home. If you are familiar with how does DNS and unbound work, feel free to skip to the Installation section. Here is the complete list of hardware and accessories we have used for this project: We decided to install unbound on a dedicated system connected directly to our router via ethernet. This guide will not go through the Pi-hole installation steps. To verify if your distribution is supported, check out Supported Operating Systems section in the Pi-hole documentation. You can install and configure Pi-hole with the command below on any distribution which utilizes systemd or sysvinit. The Pi-hole is a DNS sinkhole that protects your devices from unwanted content, without installing any client-side software. This guide is intended for unbound installation in conjunction with Pi-hole and therefore Pi-hole is the only prerequisite. Unbound runs on FreeBSD, OpenBSD, NetBSD, MacOS, Linux and Microsoft Windows, with packages available for most platforms. To help increase our online privacy, unbound supports DNS-over-TLS and DNS-over-HTTPS which allows clients to encrypt their communication. ![]() Pi-hole using Unbound for DNS.Unbound is a validating, recursive, caching open-source DNS resolver primarily developed by NLnet Labs, VeriSign Inc., Nominet, and Kirei. Note that initially, requests may take a second longer as Unbound starts building its cache of data, but as you use it, it will get faster and faster. Now your Pi-hole will ask your Unbound DNS server for addresses instead of the mainstream, upstream DNS providers, or your ISP. If you changed the port mapping on the docker run command, then make sure to use the port number you set after # sign instead. On the right, under Upstream DNS Servers, click in the text field below "Custom 1 (IPv4)" and enter the IP address of the host machine your new Unbound DNS server is running on followed by "#5335". You'll want to uncheck your currently selected upstream DNS settings on the left. Once you're logged in, you can go to Settings in the left menu, then select the DNS tab at the top of the window. For instance I useĬlick the Login button and enter your Pi-hole password. Now log into your Pi-hole by going to the IP address of your Pi-hole, and adding /admin to the end of the address. If you changed the name of the container before running the command, then change it for any commands that reference the name as well. You can verify that unbound is running without errors when the command completes by checking that it's in docker with Press Enter to run it and get unbound pulled down and started. Now paste it back into the terminal at the prompt with CTRL+Shift+V, or right-click and paste. Now, you can cat out the command with cat docker-run.txtĬopy the command by highlighting it, then right-click and copy, or use CTRL+Shift+C. Save the file with CTRL+O, then Enter, and exit using CTRL+X. Simply copy that command, and paste it into the terminal file you just created above, with CTRL+Shift+V or using right-click and paste. The command is very straightforward compared to a lot of docker commands we run.ĭocker run -d -name my-unbound -p 5335:53/udp -p 5335:53/tcp -restart=always mvance/unbound:latest It's just a text file where we'll hold our docker run command. Next, create a file inside that folder called "docker-run.txt". That way we have it in the future as well. Make a directory to store our docker run command. We will be using Docker-CE to run Unbound, and we'll be using the mvance/unbound image as well. This is about installing Unbound, and getting your Pi-hole to ask it for sites instead of asking your ISP or some other 3rd party for your site addresses. This isn't about installing or setting up Pi-hole, but here's a video that will tell you exactly how to do that. Instead, how about setup your own DNS server, and then tell Pi-hole to use that? It's really not difficult, so you should definitely get it setup. Now, imagine you went to all that trouble to get rid of those ads and tracking, but you still send all your requests right through your ISPs DNS servers, or Google's DNS servers, or anyone else's DNS servers. Pi-hole is an amazing tool with tons of functionality beyond it's main purpose of filtering out ads from your devices.
