The internet uses numbers, not names, to find computers. Domain Name System (DNS) is the internet’s directory service: It takes a human readable name, like “www.linuxlinks.com”, and converts that name to a machine readable “IP” address that your computer can use to connect to www.linuxlinks.com.
Browsers then use those addresses to communicate with origin servers or CDN edge servers to access website information. This all happens thanks to DNS servers: machines dedicated to answering DNS queries.
DNS is one of these things many take for granted that is critical to using the internet. Without DNS, the internet breaks. It’s critical that a DNS server keeps the internet working in a secure and stable manner.
DNS clients, which are built into most modern desktop and mobile operating systems, enable web browsers to interact with DNS servers.
This roundup picks some useful DNS clients for Linux. Only free and open source software is eligible for inclusion here.
