Configuring DNS & IP Addresses

Cloud 66 hostnames

Cloud 66 creates unique DNS hostnames for each application you deploy with us. All servers are accessible via their Cloud 66 DNS name which follows the following pattern:

name-of-app-and-some-numbers.c66.me

You can browse your application directly by visiting the Cloud 66 address. To do this:

  1. Log into your Dashboard
  2. Open your application
  3. Click on the Visit Site link (next to the app's name)

Failover hostnames

In addition to unique hostnames per server, Cloud 66 also offers Failover Groups - managed, quick-response DNS addresses that automatically follow the web endpoints of applications.

Each Failover Group has a unique hostname with a 9 digit prefix (subdomain). For example 958-797-516.cloud66.net. For maximum reliability, you should point your DNS at a Failover Group address.

Adding custom domains for static sites

You can add one or more custom domains to any prebuilt application managed by Cloud 66. This allows your visitors to access your site via your own preferred web address (e.g. www.mysite.com) rather than your Cloud 66 address. See below for detailed instructions.

Setting up a Custom Domain

Setting up a custom domain for your Sites app has two stages - setting up a DNS record for your domain and then enabling it in Cloud 66.

Stage 1: Add a CNAME to your DNS records

Before you enable your custom domain on your Sites app, you need to set it up to point to Cloud 66. To do this you will need to log into your domain provider and navigate to the DNS record manager (or editor) which will allow you to add a record pointing to your new site.

The next step depends on the kind of domain record you want to use. There are two types:

  • Standard subdomains (e.g. www.mysite.com or store.mysite.com)
  • Apex domains (e.g. mysite.com)

Adding a subdomain record

If you’d like your site to use a subdomain like help.mysite.com or blog.mysite.com then you will add a CNAME record pointing to ct.cloud66content.com

For example, to set up your site to use https://blog.mysite.com:

  1. Log into your domain provider and open the DNS manager
  2. Add a CNAME record with the host (or name) field set to blog
  3. Point the record to ct.cloud66content.com (the field is often named value or data)
  4. Use the default TTL (you don’t need to change it)
  5. Save (or apply) your changes

It can take up to 24 hours for this change to propagate, so you may need to attempt Stage 2 several times.

If you’re not sure how to do any of the above, google your domain providers name (e.g. GoDaddy) and the phrase “add domain record”.

Adding an apex record

If you’d like your site to use an apex domain like mysite.com or my-other-site.com then you will need to add an A record pointing to Cloud 66’s IP address (35.211.152.218)

For example, to set up your site to use http://mysite.com

  1. Log into your domain provider and open the DNS manager
  2. Add an A record with the host (or name) field set to @ or root
  3. Point the record to 35.211.152.218 (the field is often named value or data)
  4. Use the default TTL (you don’t need to change it)
  5. Save (or apply) your changes

It can take up to 24 hours for this change to propagate, so you may need to attempt Stage 2 several times.

If you’re not sure how to do any of the above, google your domain providers name (e.g. GoDaddy) and the phrase “add domain record”.

Stage 2: Enable your custom domain

  1. Log into your Cloud 66 dashboard and click on the app
  2. Click ⚙️ Settings in the left-hand nav
  3. Click the Add a Custom Domain link in the main panel
  4. Enter the custom domain you want to use and click SAVE
  5. We will now attempt to set up a SSL certificate for your domain. If your DNS record is not properly set up or has not propagated yet, this process will fail.
  6. To retry the process, click the View Certificate link and then the Request Renewal button

Adding multiple custom domains

You can point multiple custom domains at a Sites site - including apex and subdomain records from the same domain. So, for example, you can set your site to work with both mysite.com and blog.mysite.com. The only requirements for using multiple domains are:

  1. That all of the required domain records have been configured with the domain provider
  2. That all of the domains and subdomains are enabled on Cloud 66 (see Stage 2 above)

We will provision SSL certificates for each of these domains.

Editing your custom domain

You can update your custom domain at any time by clicking the Edit button and then saving the update. However bear in mind that:

  • You will need to update the DNS records for the new domain before this will work
  • Editing your custom domain will trigger the creation of a new certificate for your app
