The domain namespace is divided into regions called zones. In order to maximize availability, the InterNIC (Internet's Network Information Center) requires that every zone have both a primary and secondary DNS server. We maintain two public nameservers, ns1 and ns2. When used for primary DNS, ns1 acts as the primary and ns2 as a secondary. You only need to submit a single request for primary DNS service to enable ns1 as your primary and ns2 as your secondary. When used for secondary DNS, all of our name servers act as secondary nameservers that obtain data by way of zone transfers from the primary of your choice. You only need to submit a single request for secondary DNS service to enable our name servers as secondary name servers for your zone. | |
