<div>
<p class="MsoNormal">I was testing with this a week ago, and what I found was the reverse domain works just like you indicate, in that if you specify it as 10.in-addr.arpa, the PTR entries will just be longer; you will see PTR entries like <b>y.x.32</b>, and
<b>x.y.48</b>...<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Seemed like everything worked alright, though I assume the lookup time in this case may be a little longer if there are 1900 PTR entries under one reverse domain... Worse case, you create 16 reverse domains to speed up the resolution of
the PTR entries...<o:p></o:p></p>

<p class="MsoNormal">I was not sure what you meant by "how often" and "how many". Can you clarify?<o:p></o:p></p>
