Are my name servers different subnets?

The nameservers for our newly provisioned servers are different subnets.

This means the IP's of the two name servers are separate c-class IP's. This is preferred, as it provides a backup address in case the DNS service is unavailable at the first IP.

You will find your correct name servers and private name server information in your New Account email. (You get a New Account email after you pay for a new hosting plan.)
