Step 3
If your domain name is available, you need to select Subscription, Resource group, Contact information, Privacy protection, and Legal Terms. Here, I have filled in my personal details. Next, I have accepted the privacy protection agreement. Fortunately Azure is providing Privacy Protection for free.
Step 4
In this window, you need to accept pricing. Azure Domain Service is running in association with Go Daddy.
Click "Accept" to continue.
