hi @ife Wildcard subdomains aren’t enabled by default and can only be enabled from our end. There are also a few requirements before we’re able to do so:
Either you have to use Netlify DNS so we can get you a wildcard SSL cert, or you must bring a custom wildcard certificate.
You can’t use domain aliases on the site with Wildcard subdomains enabled, just the bare domain and subdomains under your primary domain. If you try to add a domain alias then it won’t work.
The primary custom domain for the site, if it is a example.com with www.example.com setting in our UI, must be www.example.com and notexample.com!
Once the wildcard subdomain feature is enabled, you do not need to add new subdomains under the site settings. You’ll will need still need to create DNS records.
This might be a single wildcard DNS record for all subdomains (like a CNAME for *.example.com pointing to the netlify.app subdomain for the site). Alternatively, you can also create the individual DNS records to add each subdomain (like CNAMEs for subdomain-a.example.com, subdomain-b.example.com, etc.) as covered in our external DNS documentation. Both work so please do whichever you prefer.
Let us know which site and we’ll verify that it meets the requirements and get that set up for you.
Hello, @manoocher thanks for reaching out! It looks like you have an inactive Netlify Dns that needs to be removed and make your DNS at your registrar and not at Netlify. I can see you reached out to our Helpdesk. We will follow up there.
