Build Your very own DNS server with a Raspberry Pi

In order for computers to communicate with each other over the internet, all participants in the network have a unique address: Through IP addresses, clients know exactly which servers they should address. But no user can be expected to memorize the numerical sequence of the address, so instead, domain names are used. For this, there’s a domain name system (DNS): It converts numbers into domains and vice versa. To do this, clients first have to query one or more DNS servers before they get the correct address. This can cost valuable time. Therefore, it can be useful to speed up the internet connection by setting up a dedicated DNS server. A Raspberry Pi, the small but many-sided computer, provides a good base for this. We explain to you here how DNS functions and how you can set up your own home DNS server.

Equip Raspberry Pi with a static IP address

A static IP address, as opposed to a dynamic IP address, doesn’t change. The single-board computer Raspberry Pi always needs a static IP address if you want to access it with other devices over a long period of time. This refers to the private IP address of the Raspberry IP that is located by a computer within the local network as well as the public IP address of the network via which the Raspberry Pi is accessible on the internet (for example, if it’s being used as a server). But how do you provide Raspberry Pi with an IP address that always remains the same? This guide explains which options you have for linking a static IP address to your Raspberry Pi.

Set up Raspberry Pi as a VPN server: OpenVPN tutorial

The security of public internet access often leaves something to be desired. If you want to move around safely on the internet using your own VPN (“Virtual Private Network”) is a great way to do just that. By creating a personal VPN server, you also have access to the local home network via any internet connection.

To set up your own virtual, private network, you need a computer system that can function as its server. For this Raspberry Pi is a cost-effective option. You can make your own VPN server on Raspberry Pi using the free VPN server software OpenVPN, which is available to download online.

Banish Advertising From Your Whole Network with Pi-Hole

What is Pi-Hole?

Pi-Hole is a Linux network-level advertisement and internet tracker blocking application which acts as a DNS sinkhole (And optionally a DHCP server), intended for use on a private network. It is designed for use on embedded devices with network capability, such as the Raspberry Pi, but can be used on other machines running Linux and cloud implementations.

Pi-Hole has the ability to block traditional website adverts as well as adverts in unconventional places, such as smart TVs and mobile operating system adverts.Read More
