I have a problem with creating a cname record, this is my configuration I'm using ISPConfig 2 as a DNS server and I am fine, I am asked to create a subdomain with cname record only that directs to another domain without creating A record but when I create the subdomain A record is automatically created. They do not want the record but only the Cname record. If the file ptr .... Record at the gate and leave only the cname and A records for the subdomain nameserver is no longer displayed. I'm going crazy, I can not understand how to configure DNS. Any idea on how to proceed?
