Nic.it makes some preliminary tests on authoritative nameservers for any domain, and the nameservers must pass successfully the test before being approved.
Tests are as follow:
- there must be at least 2 (two) authoritative nameservers for the domain name
- the IP addresses of the nameserver specified in the form must correspond to those actually associated with them in the DNS;
- a CNAME record cannot be associated with the domain name;
- the name of the nameserver specified in the SOA record cannot be a CNAME;
- the names of the authoritative nameservers for the domain name cannot be CNAME;
- a CNAME cannot be associated with the MX record, if present;
- if, during the verification procedure, at least one nameserver gives one of the following responses:
•Not responding
•Not reachable
•Not running
•Non-existent domain
•Host not found
•Server failure
•Query failed
the procedure fails.
