Goal We are looking to setup up a minimal forwarding DNS server on Ubuntu 16.04. After that we will see how to use nsupdate and dig to verify our configuration. Prerequisites A VM running Ubuntu 16.04 with BIND installed You need root access for the VM External DNS server information We are going to use google’s DNS servers (22.214.171.124 and 126.96.36.199) as our external servers. In case a query can’t be resolved by our DNS server it will forward the request to the external server. Domain information We need to know the domain topology we want our DNS server to manage.
