<div dir="ltr">Hey all,<div><br></div><div>Pertaining to the same discussion. Can someone validate below zone files and named.conf files?

<br>
As long as you move the above A record into the subdomain, I don't see<br>
any problem with this.<br>
<br>
You should also make sure you're more careful when editing your real<br>
zone files than you have been when writing your post, there were LOTS of<br>
typoes (NA instead of NS, exmaple for example). :)<br>
