If I have a domain with Hosting, can I have a third level with DNS Management?

Yes, it is possible to link some Third levels which have DNS Management to a domain with Hosting, both with and without mail services.

We specify that it will NOT be possible to request the change of the Authoritative NS for the Third levels, because they are not registered domain names.

 N.B. It is not possible to direct (re-direct) the third level with DNS management to the space of the second or to any shared hosting machine with Aruba, as it is not possible for the second levels registered with the DNS management offer.
