Point to: 220.127.116.11

After pointing your A Record to the IP address go to your site's domain mapping page and enter your own domain name and click "Map Domain" button.
From your site's dashboard go to Tools > Domain Mapping > click the down arrow to choose from "http://" or "https://" > in the field enter your domain name > click Map domain button.
Health status shows "Valid" when the domain mapping is successful.
We also suggest creating a CNAME instead of an A record, and point it at the root domain. Ex.: CNAME
CNAME = 'canonical name' - in this case it basically functions as saying 'get the ip address for this name from this other host name
