Use Domain Mapping to connect your domain name to Godinterest. Domain mapping is free.
1. Update your nameservers to point to your Godinterest blog url.
Right now, your domain is linked to your old host, so you’ll need to update your nameserves — specifically, your DNS settings.
2. Set your newly mapped domain as your blog’s primary address.
When the DNS changes are complete, go back to the Tools page, check the button next to the domain you just mapped to your blog, and click “Update Primary Domain.”
