DreamHost makes it super easy to remove or require the “www” from your domain name automatically. While some people prefer to not use “www” in their web site URL some prefer that it always be there.

Whether it be for SEO purposes or just for aesthetics, you can easily set this up via your Web Panel > Domains> Manage Domains.  Click “Edit” for the domain you’d like.  Select  the Always add “www.” or Always Remove “www” option, and click Submit. The change should take effect within 15 minutes.

If you would rather go the .htaccess route or learn more check out the Support Wiki’s pages on: Removing the “www” from your domain, and Requiring the “www” for your domain.
