Configuring Linux DNS Settings
Correct configuration of Domain Name System (DNS) settings can yield benefits in privacy, security, and availability, explains Jonathan Terrasi. “Yet despite how straightforward it is in theory and historically was in practice, customizing your device’s DNS is no longer an intuitive matter.”
DNS is often considered the “phonebook” of the internet, Terrasi notes. “When you enter a URL containing a domain, your computer asks a DNS server for the IP address associated with the domain. Once the DNS server responds with the answer, your computer dials up that IP address and connects.”
In this two-part tutorial, Terrasi explains how systemd handles DNS and shows how to “create nuanced DNS resolution behaviors for specialized use cases.”
