Hi, @vitorpy. We have more information about the NETLIFY and NETLIFYv6 type DNS records here:
Please read that support guide above for an in-depth explanation of how these records behave with our service. The three key points there are summarized as:
- These records are locked by default and can be unlocked by our support team.
- These records only connect domain names to IP addresses.
- These records do not control which site the domain name is linked to (if any).
I’ve unlocked all those records for the Netlify DNS zone now. You can delete those records if you choose to.
One last thing, the DNS zone should be deleted if it will not be made active again. Meaning, delete the whole zone not just individual records unless Netlify DNS is being used.
An unused DNS zone will cause issues renewing any automatic Let’s Encrypt SSL certificates for this custom domain. Again, please either reactive or delete that DNS zone at Netlify.
