Many hosted services, like Tumblr, Big Cartel, GitHub Pages, or Shopify, … just to name a few, allow you to set up a custom domain to point to your account with them, and the most common set up for this is using
ns2.mainnameserver.com. If you registered your domain with us this is the default set up.
To add a new
CNAME record you need to log in to the domain manager.
Once inside the domain manager you will find the DNS management feature where you can see all your existing records.
When creating a new
CNAME record there are two things we need to know:
- What subdomain you want to use. For example, if you want to add a
blog.example.comas your Tumblr’s blog custom domain, the subdomain would be
blog. Note that you can not create a
CNAMErecord for the root domain, so the subdomain field can not be empty.
- What Fully Qualified Domain Name (FQDN) will be used to resolve the chosen subdomain. Following the example above, this would be
domains.tumblr.com.. Note that it is important that you add the dot at the end of the domain name (
domains.tumblr.com) as otherwise it would be understood as a subdomain of your domain and not a domain outside.
Click on the “Update DNS” button to save the new record.
The record should now appear in the list and show as pending. This indicates it has been changed recently and may not yet be visible across the internet. This can take up to 24 hours.
