Unable to update the name servers for .it

We are trying to update a .it domain over at europregistry with the nameservers provided by Cloudflare.

We keep getting the following error

You must make sure that the name servers you provide fulfill the following requirements.

(i) All name servers that are provided must be active and authoritative for the domain.

(ii) At least one name server provided must exist on a different IP address subnet. An example of a different subnet address is when the one of the first three segments of the IP address are different to the other name server.

To ensure your name servers are configured correctly, please use the official .IT name server zone checking tool. This can be found online at:

dns-check [dot] it

Using this zone check tool will help you identify the details of any error. Please make sure you receive a successful notice using this tool before re-submitting your domain name delegation request.

Alternatively, you may use our name servers and use the DNS Forwarding feature to manage the zone for your domain name.

Is there anything we should be doing different or can provide from a Cloudflare point of view?


What’s the domain and which nameservers are you trying to set? Generally though → Can't set nameservers - (Inconsistent Set of NS / Nameserver not authoritative)
