You can manage your nameservers for domains registered with SixFive in your My SixFive account. By default we use CloudFlare, so you get all those benefits. 

Before you move your domain, please note that once you do, you become responsible for your DNS records, and if you were to loose a record critical to (for example) your email delivery, wewill tell you what they should be, but you'll need to learn how to manage and add those records yourself. 

Here's how to change your Nameservers: 

Login to My SixFive

2. Click on Domains

3. Click on Down arrow to reveal Domain Options

4. Click on Manage Nameservers

5. Click on Nameserver 1, and update the Nameserver

6. Repeat for other Nameservers as necessary

7. Click on "Change Nameservers" to save your changes
