Configure a Domain - Yahoo
The custom domain name feature allows you to setup your Weebly site with a domain name you've already registered through Yahoo / AT&T Small Business. This is a relatively difficult task if you don't have any experience with editing your domain records, so we recommend that you register your domain through Weebly if you are looking to buy a new domain.
To configure a domain with Weebly that was registered through Yahoo:
1. Login to your Yahoo Small Business Account:
2. Go to the Domain Control Panel for the domain you want to point at Weebly:
3. Select the Manage Advanced DNS Settings option:
4. Yahoo usually has two A Records and a CNAME record setup for your domain like those seen here:
Edit each of the three records to point them to the Weebly IP: 199.34.228.100. Each record's destination will look very similar to this when you enter the IP:
Submit each change as you make it. Once you've edited all three records you're done!
