Any resolving client capable of reaching our servers will be able to get the domain data from our servers. You will be able to use the host names that we configure to reach your servers from the internet, as well as find out the host names by querying the IP addresses. The machines that we will be configuring will have the following properties: PurposeĪfter you are finished with this guide, you should have the first two servers configured with NSD to act as authoritative-only server for your zones. You should substitute your own domain to follow along. We will be using the dummy domain for this guide. We will also provide configuration data that will let clients reach a web server on a third host.

It can also refer resolvers to other name servers for zones that it has delegated away.įor the purposes of this guide, we will be configuring two servers with NSD software to act as our primary and secondary servers for our zones. It only responds to iterative requests for the zones it controls. If you need help understanding what an authoritative-only DNS server is used for, check out our guide on the differences between DNS server types.Īs an authoritative-only DNS server, NSD does not provide any caching, forwarding, or recursive functionality. Prerequisites and Goalsīefore you begin with this guide, you should be familiar with some basic DNS concepts and terminology.

In this guide, we will demonstrate how to install and configure NSD to securely administer our DNS zones on Ubuntu 14.04 servers. Without the need to ever worry about recursion or caching, this server operates with high performance and a lower footprint. A piece of software known as NSD is an authoritative-only DNS server that is ideal for managing DNS zones authoritatively. To solve this problem, alternative DNS servers have been created that specialize in a single area of DNS resolution. It also means that the software itself will be less responsive for any one task. This additional complexity makes management more difficult.
Most of the time there are huge chunks of functionality that your configuration has no need for. However, that flexibility also means that Bind is not optimized for any one task.

Software like the Bind DNS server is incredibly flexible and can be configured to operate as many of the components in the overall DNS hierarchy. DNS zone management is a vital duty, but can be bewildering, especially when attempting to get started. Setting up a DNS server to be responsible for domain names can be a complex task even for seasoned administrators.
