Hello, All, Does anyone have some good documents on the proper usage of reverse DNS PTR records? I am trying to reconcile the class C which is allocated to us but I don't know which hostname I am supposed to use in the PTR record.
For example say I have an IP address 199.218.9.5. If all of these hostnames... acme.com ftp.acme.com mail.acme.com ns1.acme.com www.acme.com point to that same IP address, which one of them do use in the Reverse DNS? Is there some sort of order of precedence, e.g. 1. NS - If an IP is being used by a Name Server always use this as the hostname. 2. MAIL - If an IP is NOT being used by a Name Server but it is being used by a Mail Server use this hostname. 3. WWW - If an IP is NOT being used by a Name Server or Mail Server use this as the hostname. etc. Is there a correct way of doing this? Or at least a standard convention? Thanks, Much!
