How best to redirect from subdomain to path

I have a domain purchased on godaddy that I’m using in netlify to host a site under this subdomain: app.dwelller.com.

I’d like to add an alias so that both www.dwelller.com and dwelller.com are simple proxies that render the page defined at app.dwelller.com/landing? Would this be via a CNAME record in godaddy?

Is this an antipattern? If not, what’s the best way to go about doing this? If so, what is a better approach here?

No, a CNAME record does not work in like this. See

You could potentially configure a redirect for both the apex and www subdomain to app.dwelller.com/landing, or deploy the landing as a separate site and attach the domain to it.
