ptr zones are the same way delegated as any other zones<br>

dns zones are not downloaded<br>
<br>

<br>
that don't scale given that most customers just have a single IP<br>
<br>
in case you have a /24 the ISP can delegate the whole zone to you, look <br>
at the authoritative nameservers below<br>

<br>
if you run a mailserver it is a must, at least when you care to deliver <br>
your mails, as well make sure your HELO-hostname matches too<br>
<br>
many sites add at least points to the sapm scoring for clients like that:<br>
<br>
warning: hostname szkoleniagospodarka.pl does not resolve to address <br>
51.75.72.176: Name or service not known<br>
<br>

<br>
well, in case of servers i prefer PTR/A matching no matter if it is <br>
supposed to send mail and the same goes for internal networks i maintain<br>
