Here is the complete procedure to add custom domain to Blogger’s blog using blogger basic settings feature.
Linking the domain name which ends with com, co.in, or any other famous extensions give a good feel to the browsers and increases the trust on the website. But domain hosting is a very costly affair now a days as many domain hosting websites started charging the customers heavily. Blogger, Google's blog service has a unique and useful feature of adding up the domain name you have registered on your name.
First of all we assume that you have purchased a domain name from any of the domain selling websites. Here follow step by step easy instructions to add custom domain to the blog in Blogger.
DNS settings for Domain switching
Go to the website where you have purchased the domain.
Login in the website and go to the domain control panel or domain settings.
Look out for Domain Naming Services Management that is DNS Management. Under the DNS management panel, you will find an option called Manage DNS. Manage DNS has the complete domain naming settings which are responsible for the page rendering by the browser.
Here under Manage DNS settings, you will find various files under categories such as A Records, AAAA records, MX Records, CNAME Records ect.
Go to A Records and delete all existing A Records under Manage DNS settings page.
Now click on "Add A Records" to add an A Record which points to Google Blogger server. You are asked to provide three details while adding the A Records viz., Host Name, Destination IPv4 Address and TTL. So don't type anything in Host Name. Enter Destination IPv4 Address as 126.96.36.199 and leave TTL as the default value only. Click on "Add Record" button to add the new A Record.
Follow the above step and add three A Records with IP addresses of 188.8.131.52, 184.108.40.206 and 220.127.116.11.
After adding the A Records successfully, you need to add CNAME Record to point to Blogger domain hosting server.
So to do this, go to CNAME Records and delete the existing CNAME Records. Click on "Add CNAME Record" button to add new CNAME Record.
In CNAME Record, type Host Name as www. And select the check box of " Type In A Fully Qualified Domain Name " and type in the textbox as ghs.google.com. keep TTL as default value only. Click on Add Record to add CNAME Record.
That's all you need to do to add the custom domain DNS settings. Log out from the domain website.
