No. Catalyst CloudScale Domain Mappings maps only subdomains, such as `www.zylker.com` or `app.zylker.com`, because a mapping works through CNAME records and Catalyst does not support mapping a base domain directly to an application URL. Catalyst also does not give you IP addresses to use in A or AAAA records. Map a subdomain, then redirect the root domain to it at your DNS provider.

1. If you added the root domain in **Domain Mappings**, delete that mapping.

2. Switch to the Production environment, open **Domain Mappings** under **Host and Manage** and click **Add Mapping**. Enter a subdomain such as `www.zylker.com`. For an AppSail app, select AppSail as the domain type.

3. Add the two CNAME records the console shows, with the subdomain as the host name, and click **Verify**.

4. At your DNS provider, set up domain forwarding from `zylker.com` to `www.zylker.com` over HTTPS.

Note: Requests to the root domain never reach Catalyst, so your DNS provider serves the redirect and any certificate for the root domain. If it cannot forward over HTTPS, ask the provider which option it offers.
