Custom Domain Name On Blogger

1.Find the control panel on your domain registrar’s website, and locate your DNS (Domain Name System) settings. In order to link your blog to your custom domain, follow the instructions below to enter your "CNAME" and "A-records."

CNAME
Where it says Name, simply enter "www" and list ghs.google.com as the Host Name. See our detailed instructions on providing CNAMEs for various registrars. If yours isn't listed, or if you run into other difficulties, contact your registrar directly and they can help you out.

A-records (optional)
The following action links your naked domain (example.com) to your actual site (www.example.com). If you skip this step, visitors who leave off the "www" will see an error page.

Enter your domain name in the format example.com, and list the I.P. addresses shown below in the "A" section. You'll need to create four separate A-records which point to four different Google IPs.
