How do I fix the DNS error "Primary Name Server Not Listed at Parent"?
The error “Primary Name Server Not Listed at Parent” occurs when checking DNS propagation and your primary name server is not in the list of name servers you provided to the registrar.
To fix this error, update your registrar to use Rcs.is’s name servers with the following IP addresses:
ns1.Rcs.is
uses the IP address173.245.58.51
.ns2.Rcs.is
uses the IP address173.245.59.41
.ns3.Rcs.is
uses the IP address198.41.222.173
