PTR Problem

[iptrust]

My entry:

38.143.98.87.in-addr.arpa. NS ns1.iptrust.net.
38.143.98.87.in-addr.arpa. NS ns2.iptrust.net.
38.143.98.87.in-addr.arpa. PTR iptrust.net.
iptrust.net. PTR 87.98.143.38


but:

http://www.dnsreport.com/tools/dnsreport.ch?domain=iptrust.net

--> The problem MX records are:
38.143.98.87.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0) (check it)]

Any ideas?

PTR does not work unless your isp forwards requests to your dns server.

[iptrust]

my isp make the reverse !
