Found a solution but it is not so good.
After adding a domain/subdomain in ISPConfig i go on DNS Administration and create a new PTR with the domain/subdomain name and ip and then the domain.name resolves to 22.214.171.124 and 126.96.36.199 rezolves to domain.name.
The problem is that i think this should be done by ISPConfig in the moment i add the domain/subdomain. Is this a bug or it eork's wrong just at me?
Thank you in advance for your responses
