Ideally the two servers should be at different physical locations.

If one DNS server is offline, the other DNS server can still response to DNS queries for your domain name.

In a previous article, I explained the steps of setting up a local DNS resolver on Ubuntu 18.04/16.04.

This tutorial will show you how to set up BIND9 on Ubuntu 18.04/16.04 as an authoritative-only DNS server with recursion disabled.

Normally you use hostnames in the NS record like The above information will be sent to a registry operator who runs TLD DNS servers via the Extensible Provisioning Protocol (EPP), so that TLD DNS servers know the hostnames and IP addresses of the authoritative DNS servers for your domain name.

After the NS record and glue record have been propagated to the Internet, you DNS servers would be responding to DNS queries for your domain name. I hope this tutorial helped you set up authoritative DNS server on Ubuntu 18.04 and Ubuntu 16.04 with BIND9.

BIND (Berkeley Internet Name Domain) is an open-source, flexible and full-featured DNS software widely used on Unix/Linux due to it’s stability and high quality.

It’s originally developed by UC Berkeley, and later in 1994 its development was moved to Internet Systems Consortium, Inc (ISC).

BIND 9 is the current version and BIND 10 is a dead project.

Instead of waiting for the slave DNS server to make contact, the BIND master will notify the slave when changes are made to the zone.

This can considerably reduce the time to propagate zone changes to the Internet.

However, taking two roles at the same time isn’t advantageous.

It’s a good practice to separate the two roles on two different machines.

Each server needs only 512MB RAM and here are the hosting providers that I recommend. Once you have bought two servers, install Ubuntu on them and follow the instructions below.
