Here are the following steps to setup your Blogger account to a custom domain name through your cPanel.
1. Log in to your cPanel account. (URL for Cpanel like http://example.com/cpanel, replace example.com with actual domain name)
2. At the cPanel, click on the Advanced DNS zone editor which can be found under the Domains section.
3. Now add appropriate A Records in the fields provided, as shown below. You need to add the following 4 IP addresses for the A Records to configure your Blogger Domain one-by-one:
Type: A, Name: yourdomain.com, Address: 216.239.32.21
Type: A, Name: yourdomain.com, Address: 216.239.34.21
Type: A, Name: yourdomain.com, Address: 216.239.36.21
Type: A, Name: yourdomain.com, Address: 216.239.38.21
4. To add the CNAME records, select CNAME from the drop down menu choose CNAME.
5. In the Name field, add the name of your domain with www. In the CNAME field, write ghs.google.com for syncing your domain with Blogger.
6. Add an appropriate Time-To-Live in the TTL field.
Type: CNAME, Name: www.yourdomain.com, CNAME: ghs.google.com
Type: CNAME, Name: kjhs3udhus2.yourdomain.com, CNAME: gv-kjdgs73fjhskd.dv.googlehosted.com
Note: This is just a sample, you should refer to your blogger account for this record.
Click on Add Record to save the new configuration. Please note that editing your DNS records will have its propagation, depending on the TTL you declared.
