5) commit changes, it will popup an error<br>

Yes, that is a typo<br>

the example is pretty awkward like that , let it be more significant
like this<br>
<br>
<blockquote type="cite">@ IN ALIAS 60 <a
class="moz-txt-link-abbreviated" href="http://www.google.com"
moz-do-not-send="true">www.google.com</a><br>
www IN CNAME 60 @.</blockquote>
<br>
after I've applied with success above example.com zone , proceeding
with an nslookup at this point gave this result<br>
<br>
<blockquote type="cite">> example.com<br>

<br>
even checking cname records leads to same result<br>
<br>
<blockquote type="cite">> set q=cname<br>

href="http://www.example.com" moz-do-not-send="true">www.example.com</a><br>
;; communications error to 127.0.0.1#53: timed out<br>
