Thanks for reaching out and welcome to Netlify’s Support forums!
I see you have configured Netlify DNS for the domain here:
However, you are using domaincontrol.com name servers instead of the Netlify name servers.
host -t ns pierobon.net
pierobon.net name server ns69.domaincontrol.com.
pierobon.net name server ns70.domaincontrol.com.
I also show that you have External DNS setup for the domain:
A Record for pierobon.net pointing to 126.96.36.199:
pierobon.net has address 188.8.131.52
pierobon.net mail is handled by 10 aspmx.l.google.com.

CNAME Record for www.pierobon.net pointing to marcopierobon.netlify.app:
www.pierobon.net is an alias for marcopierobon.netlify.app.
marcopierobon.netlify.app has address 184.108.40.206
marcopierobon.netlify.app has address 220.127.116.11
marcopierobon.netlify.app has IPv6 address 2600:1f18:2489:8200::c8
marcopierobon.netlify.app has IPv6 address 2600:1f18:2489:8202::c8
We have a Support Guide here on how to detect a inactive DNS Zone:
The solution is either to delete the DNS Zone as outlined here. Or to use Netlify’s name servers mentioned here. If you decide to use Netlify’s name servers, you’ll need to remove the External DNS configuration of the A Record pointing to 18.104.22.168 and the CNAME Record pointing to marcopierobon.netlify.app.
Having both External DNS and Netlify DNS configured can cause issues with the SSL Certificate getting generated or renewed.
