Updating root zone file
Right click on the server, some networks can have listed more DNS Servers, where you want to update the Root Hints to open the context menu and click on Properties.In the Properties window go to the Root Hints tab and click on Copy from Server.The authoritative name servers that serve the DNS root zone, commonly known as the “root servers“, are a network of hundreds of servers in many countries around the world.The 13 root name servers are operated by 12 independent organizations.As you can see in my case several IPv6 addresses are added and on the h.even an extra IPv4 address.Click on Apply and OK to close the Properties window.If you follow the example of the non-CDB instance, it will only be upgraded in the root container.
To get a reliable source, go to the root server’s website and search for a IP address here.
For this blog post the screenshots are taken from a DNS Server running on Windows Server 2008 R2, but for Windows Server 2003 to Windows Server 2012 R2 there are no big differences how to configure this, from Windows Server 2016 and Windows 10, things can be easy configured and scripted with Power Shell, see the bottom of this post.
First of you need to start up the DNS Manager, you can find this under Administrative Tools or run with MMC shortcut
You can change which service your domain uses for its website and email by managing its DNS records (also known as zone file records).
How you access your DNS records depends on where your domain is registered and hosted.
