Thanks for the quick response.<br />
<br />
One question missed:<br />
<br />
Are all zones related to a specific subnet?<br />
<br />
<br />
I looked at the Anycast link. The article doesn't really do a good job at explaining it in my view - it seems to assume a lot of knowledge on the part of the reader. &nbsp;Can you perhaps give a more layman explanation of Anycast versus unicast?<br />
<br />
<br />
<br />
Also while not wise to put the secondary zone on the same as the host can it actually be done? &nbsp;Would there be a noticeable problem if it were?<br />
<br />
<br />
Thanks for further info.

<div>
Thanks for the additional input.<br />
<br />
in regard to the following response:<br />
<br />
&nbsp; &nbsp; &nbsp;&quot;Are all zones related to a specific subnet? <br />
<br />
No. &nbsp;Records in a zone can point to any IP.&quot;<br />
<br />
What about reverse lookup zone? &nbsp;Is it not tied to a specific subnet?<br />
<br />
Also as far as the secondary zone I understand it would not be a good practice but I am just curious whether it's verboten completely. In other words when I go into the Windows DNS server holding the Primary Zone file and I try to create a Secondary Zone file and choose the exact same server as the Primary will it let me do it? &nbsp;Will the option be greyed out?<br />
<br />
Thanks in advance.

<div>
Thanks. Can I have more than one reverse look up zone if I have multiple subnets?
</div>


<div>
Sorry for the delay in responding. &nbsp;How would I do that with Windows 2012 R2 - list multiple reverse look up zones attached to different subnets?
</div>


<div>
You just create multiple reverse zones. &nbsp;I'm not sure what you mean by &quot;list&quot; them.
</div>


<div>
Per the instructions on Technet:<br />
<br />
<br />
<br />
&quot;&nbsp; &nbsp; In Control Panel, double-click Administrative Tools and then double-click DNS .<br />
<br />
&nbsp; &nbsp; Optionally, if the server to which you want to add a reverse lookup zone does not appear in the list, right-click DNS , click Connect to Computer , and then follow the instructions to add the desired server.<br />
<br />
&nbsp; &nbsp; To display the zones, click the server name.<br />
<br />
&nbsp; &nbsp; Right-click the Reverse Lookup Zones folder, and click New Zone . A zone configuration wizard appears.&quot;<br />
<br />
So it is at the last step &nbsp;that I can create more than one zone?
</div>


<div>
Sorry for the long delay. All cleared up now.

These questions apply to both Windows and non-Windows platforms.<br />
<br />
Can there be two primary zones? What would be the situation where it might apply?<br />
<br />
Can the secondary zone be located on the same host as the primary zone? &nbsp;What would be the situation where it might apply?<br />
<br />
If I have two DNS or more DNS servers, in there one that is the 'main' one?<br />
<br />
Are all zones related to a specific subnet?<br />
<br />
Thanks in advance for any assistance.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
