When I try to add an “@” Record it is not working, why not?
A free standing “@” is used to denote the current origin, it is symbolic only, and not a real DNS record type.
Some registrars like Godaddy use this to symbolize the naked/root/non-www version of the site.
Start by going to your Manage Domains Page :
Click the DNS link under your domain:
Then on the next page you will see your custom DNS Area:
Name: leave blank for naked/root domain
Type: A , TXT, or any record requiring the root domain.
