<div dir="ltr">Hi Sebastian,<div><br></div><div>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>...</div><div><br></div><div>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...</div><div><br></div><div>I was not sure what you meant by "how often" and "how many". Can you clarify?</div><div><br></div><div>Jason</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Feb 8, 2017 at 6:04 AM, Wessel, Sebastian <span dir="ltr"><<a href="mailto:Sebastian.Wessel@takko.de" target="_blank">Sebastian.Wessel@takko.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
