You are seeing this error because you’ve purchased the No-IP Plus Managed DNS service for your domain. The domain you declared in our system does not have its nameservers set to the No-IP name servers. In order for our DNS products to work with your domain, you will need to set them to:
If your domain registration is with No-IP, you can manage your name servers by clicking on the “My Services” > “Domain Registration” tab. Then selecting ‘Configure’ next to the domain you want to update.
Pull down the Name server, set “No-IP Plus Defaults” and it will auto populate the name servers for the Plus DNS service.
Note: Domain names will need to take a mandatory 24 – 72 hour propagation period to fully propagate to all of the root DNS servers.
