.IT domain name activation
The Italian registry will only accept .IT domain name registrations that have DNS which comply with their norms. In other words, they must pass their zonecheck.
If you launch your domain name creation at Gandi with DNS that are not set up correctly (ex. do not have an SOA for the domain etc.), then the registry will suspend the domain.
They periodically test your domain to see if your DNS pass their test, and will only activate the domain name if it passes the Zonecheck. If the domain continues to not pass the zonecheck, then the domain will remain suspended and many not be used.
