Hi,
Please let me know if this setting is correct
On DNS Management:
Name: mydomainname.com
Type: PTR
Value: 4.3.2.1.in-addr.arpa

(if 1.2.3.4 is my IP)

Best Regards,
Star Network.

Why do you need a ptr record for localhost ip? Why not just set it in /etc/hosts

Ive never heard of anyone trying to set a ptr on 127.0.0.1 ... sounds useless.
 
Hi,
I talk about PTR for hosted domain (Internet)
not for localhsot
the IP 1.2.3.4 is just for example...

As replied by tomtom901 you can only manage your own rDNS if your upstream provider of the IP# has delegated the authority to you. We can't help you figure that out because you haven't given us the real IP#.

So ask your IP provider.

Your colo(?) provider needs to delegate the authoraty for that IP or subnet to you before you can manage rDNS.

I know,
we just speak on phone (with my data center)
and thy toll me that I can manage rDNS (PTR) this address...

@nservices:

The IP# you sent me via PM is assigned to these two nameservers:

sdns.goldenlines.net.il.
and
pdns.goldenlines.net.il.

Unless these are YOUR nameserves, then you cannot manage your own DNS.

The way you can tell if you have authority to manage your own DNS is to run this from the command line:
Code:
$ dig -x 1.2.3.4 +trace
Note that the $ is not to be typed in; it's there to show you that you can run this command as a non-privileged user. Note also that you must replace the 1.2.3.4 with the IP# you're checking.
