Initial Domain Name
When you create an Azure subscription, an Azure AD domain is automatically created. This instance of the domain has an initial domain name in the form domainname.onmicrosoft.com.

Custom domain name
The initial domain name can’t be changed or deleted. You can however add a routable custom domain name you control. This can help simplify the user sign-on experience (contosogold.onmicrosoft.com, could be assigned to contosogold.com)
You must be a global administrator to perform domain management tasks.
Domain names in Azure AD are globally unique.
Domain name verification
When an administrator adds a custom domain name to an Azure AD, it is initially in an unverified state.
Azure AD won’t allow any directory resources to use an unverified domain name.
Verification is performed by adding a DNS record.
Azure DNS Zones
A DNS zone hosts the DNS records for a domain.
to start hosting your domain in Azure DNS, you need to create a DNS zone for that domain name. Each DNS record for your domain is then created inside this DNS zone.
Delegate DNS domains
To delegate your domain to Azure DNS, you first need to know the name server names for your zone.
Each time a DNS zone is created Azure DNS allocates name servers from a pool.
In the registrar’s (the company where you registered your domain) DNS management page, edit the NS records and replace the NS records with the ones Azure DNS created.
DNS record sets
A record set is a collection of records in a zone that have the same name and are the same type.
private DNS zones
When using private DNS zones, you can use your own custom domain names rather than the Azure-provided names.
