I am maintaining a DNS and mail server in win 2003, and the ISP made me authoritative for the domain. They say:
----- Start of the email received from the ISP--------
The reverse ip zone is currently being delegated to the following nameservers:
You will need to verify with your current DNS provider whether they will accept IP delegation and have them set up the reverse zone and add pointer records as needed.
It is a common misconception that the owner of the IP block has to create the PTR records or only the owners of the IP address can add the PTR record, but that is not the case.
Please refer to: RFC 2317 http://www.faqs.org/rfcs/rfc2317.html for more information on IP delegations.
------------- End of the email from ISP -------------------
How do I define these cnames and ptr records in my DNS, I am confused.
Thanks in advance.
