You'll receive an email like below:
The email might take a few minutes to be delivered - so please be patient. Do not forget to check it in spam if you haven't received it for a while.
Click on the link included in the email.
From the link that opens, enter the email address that you have used, and the password that you want to use for the account. You'll need to enter the same password twice to confirm. Click on "Submit" to confirm the change.
Once confirmed, you will be redirected to the login page - enter your email address and password that you just set and click on "Sign In" to get into your account.
In the interface, you will find all the domains registered under your account with us. Click on the domain name you want to manage. For demonstration purposes - we're doing this for "babalguru.com"
Click on "DNS Management Panel" for the domain and then click on "Configure Now"
The domain zone records are managed from where the domain is pointing at. So, you will need to set the domain nameserver to that of the domain registrar to be able to use the DNS management option. So, click on "Fix Name Servers Automatically" to change the nameservers as shown below:
Once you do so - the nameservers for the domain are automatically changed and anything you set under "DNS Management Panel" would go into effect.
To properly connect to blogger - you will need to add 4 A-records and 2 CNAME records. The 4 A-records are always the same and so is 1 CNAME record. The remaining CNAME record is unique to each domain.
List of A-records to add
216.239.32.21
216.239.34.21
216.239.36.21
216.239.38.21
All these records need to be pointing to your main domain so this is how you add them:
Similarly, add the remaining 3 records - this is how the interface would look like as you add them all:
The other record that you need to add is two CNAME records so click on "CNAME" from the top in the DNS Management panel and enter the records as required.
List of CNAME records to add
www => ghs.google.com [This is same for all the sites with blogger]
ukdsxx7ohscv => gv-hevdfoqdd3ukx5.dv.googlehosted.com [This is unique with all the sites - see step 4 in the below section "On the Blogger side" to know this record]
This is how you can add the CNAME record:
Similarly, add the second record as well.
Please allow few minutes to some hour for the records to fully resolve. You can use tools like this to check and see what's the propagation status for the record:

Also, check "Redirect domain" such that it's ON. The above screenshot has it at OFF but clicking on it will turn it ON. What this does is redirect the traffic to "www.babalguru.com" for the website
