Domain Name System (DNS) configuration on Windows Server 2016, topics covered include the following:
* Installation and Configuration of DNS Services – Explanation of how to install DNS with a walkthrough guide
* Creating and managing DNS Zones – Deals with primary, secondary and stub zones
* Creating and managing DNS Records – Covers different types of DNS records
* Explanation of special record types and reverse DNS – i.e. TXT records and PTR records
* Root Zones and Nameservers – Settings dealing with where DNS goes to if it can’t find a resource record
* Load balancing – Balances traffic between multiple servers
* Configuring DNS Scavenging – Deals with clearing old and unused DNS records – use with care!
* Securing DNS in a production environment – Prevents potential DNS based attacks
Ideally, any practice should be done on a test environment, as some configuration changes can have wide-spread impact on your organisation if done incorrectly. As with any changes to a production environment, you should be sure to follow your organisation’s change control processes as appropriate.
Note that this can vary largely from organisation to organisation, because most of them, and especially the larger ones, will have this in place and often you can only get non-emergency changes approved once a week, at least in my experience.
