Set up custom domain in free Blogger

The following are the steps to set Managed DNS for Blogger Custom Domain :

1. Go to your blog account and click on Basics under the Settings tab. In thePublishing section, click the link to Add a custom domain (sometimes this link is shown as Setup a 3rd party URL for your blog). 
2. Type the URL of the domain you’ve purchased, keeping in mind that it must begin with www in order to work. After that, click Save button. 
3. You should see an error message, and two CNAMEs listed below. Each CNAME is composed of two parts – ‘Name, Label or Host field’ and ‘Destination, Target or Points Tofield’. The first CNAME is the same for everyone, Name being “www” and Destination “ghs.google.com.” The second CNAME is particular to your blog and your Google Account, and is therefore different for each person. This CNAME will used in SRS-X Managed DNS settings. 
   
4. Leave this Blogger Setting panel for a while. Then open your SRS-X panel and go to Domain Details page. Click Managed DNS (manage)
