Secondary DNS Service

The secondary DNS service allows you to leverage our geographically diverse and redundant name servers and give you full control over your domain names.

Many of our customers utilize this service in a "Hidden Master" configuration which allows them to push updates to our name servers while keeping their own server hidden from the world. A key advantage to this setup is that your Master server can go down at anytime and our name servers will continue to answer DNS requests for you.

In addition to your own DNS server(s), you will need to include our authoritative nameservers as NS records:


You should allow notifies and transfers from using the following example:

zone "" {
        type master;
        file "";
        allow-query { any; };
        allow-transfer {; };
        also-notify {; };

Also you must allow both TCP and UDP traffic from port 53 to port 53 in order for transfers to work.
