I've got a domain hosted (DNS only) on Dreamhost. I've got www.mydomain.com CNAME'd to my web app on heroku, I would also like to CNAME just the domain (mydomain.com). Ofcourse, you can only CNAME subdomains.

What should I do to make mydomain.com point to my heroku app, or even redirect to www.mydomain.com?

Heroku's documentation on the matter references DNSimple's ALIAS records. If Dreamhost doesn't offer something similar, you'll need to run a small server handling the apex record, use a service like wwwizer.com, or switch DNS providers to one like DNSimple.

Here's a great write up on how to work around Dreamhost's setup to use custom domains for your Heroku App.

Basically you create a www cname with the value of your custom heroku app address, then you redirect your @ root traffic to your www sub-domain.
