Yes, in the general case. DNS supports this, bind zonefiles support this. If you're using a management UI, you'll need to check what's supported by that.

; ...
*.foo  IN A

Note that if you create another record for an item in foo, then that will stop the wildcard from providing a record. Wildcards only match where no other name matches. So you'll need to explicitly provide the data that the wildcard would have provided.

; ...
*.foo       IN A    IN TXT  "Fred was here"    IN A

Thanks - that is helpful. Not sure if my registrar supports this through its UI. – eft Jan 18 '11 at 21:19
If your registrar is serving your DNS records, you can call them and ask them to help you set it up. – cwheeler33 Jan 18 '11 at 21:39
