Bind updating root hint data file
Don’t forget the dot(.) after as it is required for the domain to be FQDN (Fully Qualified Domain Name) and without it, BIND won’t work.

Ubuntu 18.04 LTS uses systemd-resolve to resolve DNS hostnames. In this section, I will show you how to set your own DNS server as the primary DNS server on Ubuntu 18.04 LTS using systemd-resolve.

Without DNS server, you would have to type in the IP address directly if you wanted to visit example.com, which is of course very hard to remember.
Here, IP_ADDR is the IP address of your BIND 9 server.
Now save the file and restart your computer with the following command: As you can see, the primary DNS server is set to 192.1, the one that I set earlier.
A zone file holds information about a certain domain name and its subdomains. For example, the information about domain/zone would be stored in plain text format in a zone file such as db.in /var/cache/bind directory.
Now I am going to create a simple zone file for and show you how to set up your own DNS names with BIND 9.
