How to Configure alias domain redirect at DNS level?

Is this even possible?

I own widget.org which I use, but I also own widget.com.

I would like to setup widget.com to redirect to widget.org:

widget.com/anything => widget.org/anything
anything.widget.com => anything.widget.org
anything.widget.com/anything => anything.widget.org/anything

Ideally, I would like to set this up at the DNS level.

Is this possible?

(If it is relevant, GoDaddy is my domain register, and widget.com is currently parked with them.)

There's no concept of "redirection" in DNS.

The setup you describe is usually achieved as follows:

  1. setup DNS for example.org ("A" record with address of webserver)
  2. setup DNS for example.com ("CNAME" pointing to example.org)
  3. configure webserver -- either
    • "redirect" example.com requests to example.org, OR
    • serve the same pages for both domain names

If you care about google ranking etc, you want to redirect to a single canonical hostname (example.com, as well as www.example.com and www.example.org, should all redirect to example.org).

Point all the domains at one server.

On that server install a
file with mod_Rewrite that tests what was asked for and issues a redirect if necessary.
