Changeing namerservers: Nameserver not available. DNS name and Reverse-DNS name should match?

[pgm2608]

Hello.

I have successfuly changed my nameservers for mydomain1.com to:

arnold.ns.cloudflare.com

elinore.ns.cloudflare.com

But changeing for the same domain namerservers to:

dns1.mydomain2.com (which points to the same ip as arnold.ns.cloudflare.com)

dns2.mydomain2.com (which points to the same ip as elinore.ns.cloudflare.com)

gives "Nameserver not available".

DNS name and Reverse-DNS name should match?

Thank you.

Regular DNS settings are not enough for nameservers because the nameservers say where to find the DNS (like a map to itself, but you don't know where the map is).

Here are the steps to register host names, commonly referred to as "glue records".
