* [Create an A record for all your Rackspace nodes](#create-a-record-for-all-rackspace-nodes)

<h3 id="create-a-record-for-all-rackspace-nodes">Create an 'A' record for all your nodes</h3>

This example creates a  new "mydomain2.com" zone at Zerigo and an A record for all your
Rackspace nodes. Value for the A record is the Node's first public IP address.
