Ubuntu 20.04 Server: How to change DNS and domain name. In the new Ubuntu version, you cannot change /etc/resolv.conf. You can change it. But it won't last a restart. It will be replaced by systemd-resolved. I wanted to change the domain name and DNS/nameserver.
Change DNS using the Ubuntu Terminal. If you are a hardcore programmer and don't like fixing things using the user interface, then need not to worry. You can also change the DNS settings using the built-in terminal. To simply learn how to change the DNS settings in Ubuntu using terminal kindly following the steps below: Example: Changing DNS server settings on Ubuntu.

By default, ubuntu will use the DNS domain converted to uppercase (EXAMPLE.COM) as the realm. Key Distribution Center: (KDC) consist of three parts: a database of all principals, the authentication server, and the ticket granting server.
Regardless of the distribution of Linux that you are using (such as Ubuntu, CentOS, Debian, Arch, Redhat, etc), the process of determining what DNS servers are currently being used for domain name resolution is the same. To determine what DNS servers are being used, you simply need to view the contents of the "/etc/resolv.conf" file.
Domain Name Service (DNS) Domain Name Service (DNS) is an Internet service that maps IP addresses and fully qualified domain names (FQDN) to one another. In this way, DNS alleviates the need to remember IP addresses. Computers that run DNS are called name servers. Ubuntu ships with BIND (Berkley Internet Naming Daemon), the most common program

DNS (Domain Name System) is a fundamental facilitator of several networking technologies such as mail servers, Internet browsing, and streaming services e.g. Netflix and Spotify, among others.. It works on a special computer called a DNS server - which keeps a database record of several public IP addresses along with their corresponding hostnames in order for it to resolve or translate Change DNS using the Ubuntu Terminal.
