After publishing the article “Configure Custom Domain and HTTPS in Netlify”, one reader asked in the comments if the same instructions could be used to set up a custom subdomain. So in this post, I expand on my answer.
A subdomain or child domain is an extension of your primary domain name.
Subdomains can be used not only to organize and navigate to different sections of a website but also to publish different websites.
Since I own the
kiroule.com domain, I could have published my blog under the
blog.kiroule.com subdomain. Also, a subdomain can contain multiple levels, for instance,
You can create multiple subdomains in your main domain. The exact number of subdomains that can be configured should be checked with your domain registrar. For example, Namecheap allows you to use up to 150 subdomains per domain name.
Therefore, if you decide to use a subdomain for your website when hosting it on Netlify, given that the domain name is not registered with Netlify and comes from an external registrar like Bluehost, GoDaddy, Namecheap, etc., you can follow the steps that I outlined in the article “Configure Custom Domain and HTTPS in Netlify.”
The difference will be in configuring the
ALIAS Record properties in the “Configure DNS Records” step.
Here is the configuration with the primary domain:
Type: ALIAS Record Host: www Value: [name-of-your-site].netlify.app TTL: 5 min
With a subdomain, you must add the subdomain name as a suffix to the
www in the value of the
Type: ALIAS Record Host: www.[name-of-your-subdomain] Value: [name-of-your-site].netlify.app TTL: 5 min
As for me, after creating my blog and setting up the
kiroule.com domain and HTTPS in Netlify, I wanted to use a subdomain to publish another website, also hosted on Netlify.
So I have a test website https://bilberry-sandbox.netlify.app/ that I am using to test my contributions to the Bilberry Hugo theme.
To make it available as the
bilberry-sandbox subdomain of
kiroule.com, I followed the instructions from my article mentioned above, except for the
ALIAS record and Netlify custom domain set-up configuration:
Type: ALIAS Record Host: www.bilberry-sandbox Value: bilberry-sandbox.netlify.app TTL: 5 min
And now my test website is available at https://www.bilberry-sandbox.kiroule.com.
