What I’m seeing is:
I’m trying to add a NS CNAME Record so I can link all other domains I have without the need of changing all NS one by one. But when I created the NS1 and NS2 pointing to ns1.byet.org and ns2.byet.org respective I did not see any error but it does not show the type. Because of that I do not know if I have the correct type or if is not supported to have NS.
I’m using this software:
I’m using the CNAME Records option inside CPanel.
I’m sorry, but what do you mean by creating an “NS CNAME” record? A DNS record always has a single type, of which both NS and CNAME are examples. A record can be one of those two types, but not both.
If you want to setup whitelabel nameservers for your own domains, I would like to start by saying that we officially don’t support it. You can try to make it work, but I can’t promise you that it’s possible and won’t lead to issues later on.
I’m not sure CNAME records are supported for NS records. You could try of course (or try to make sense of the official DNS specifications) but no guarantees about that it will work. You could move your own domain to third party nameservers and add the A records to point to our nameserver IPs, but even that’s at your own risk.
And note that our nameservers are configured to respond as epizy.com, not your own domain, so many DNS validators will not like your settings.
