How To Install mkrdns on CentOS 8
Introduction
In this tutorial we learn how to install mkrdns on CentOS 8.
What is mkrdns
mkrdns automates the tedious procedure of editing both forward and reverse zones when making changes to your zones with likely no changes to your current configuration file. mkrdns does this by reading through all of the primary/secondary (master/slave) zones in your configuration file (either named.boot or named.conf). It will then automatically generate the reverse zone entries (IN PTR) for the networks for which you are the primary/master. It is now possible to simply edit the forward map, run mkrdns, and reload the zone. Clean, simple, and best of all, automatic. mkrdns also acts as a limited lint-like program, issuing warnings and errors if there are problems with your configuration or zone files.
