I apologize if I re-post this message.

But I had problems with the mail server and I'm not sure that it was posted.

I have tested the zone with RIPE Zone Delegation Checker and I have this error:

 

 

  >Check uniserv.uniplan.it details

                     >Args: 217.20.0.2, uniserv.uniplan.it

Can you help me to solve this error?

 

Thanks.
