Azure DNS allows you to host your DNS domain in Azure, so you can manage your DNS records using the same credentials, billing, and support contract as your other Azure services. Zones can be either public or private, where Private DNS Zones (in Managed Preview) are only visible to VMs that are in your virtual network. Our global network of name servers uses Anycast routing to provide outstanding performance and availability.
Azure DNS billing is based on the number of DNS zones hosted in Azure and the number of DNS queries received.
|DNS||PUBLIC AND PRIVATE ZONES11|
|Hosted DNS zones||￥3.98 per zone per month2|
|DNS queries/month||￥4.07/per million 3|
1 Private Zones are generally available. Billing will begin on December 1, 2019.
2 Per-zone charge is calculated daily; partial months are pro-rated.
3 Queries are aggregated within an Azure subscription for billing purposes.
What is a DNS zone? Is it the same as a DNS domain?
A domain is a unique name in the domain name system, for example “contoso.com”.
A DNS zone is used to host the DNS records for a particular domain. For example, the domain contoso.com may contain a number of DNS records, such as mail.contoso.com (for a mail server) and www.contoso.com (for a web site).
Azure DNS allows you to host a DNS zone and thereby manage the DNS records for a domain in Azure.
Do I need to purchase a DNS domain name to use Azure DNS?
You do not need to purchase a domain to host a DNS zone in Azure DNS. You can create a DNS zone at any time without owning the domain name.
However, you will need to purchase the domain name if you want to link your DNS zone into the global DNS hierarchy—this enables DNS queries from anywhere in the world to find your DNS zone and be answered with your DNS records.
Does Azure DNS allow me to purchase a DNS domain name?
No, Azure DNS does not currently support purchasing of domain names. To purchase domains, you should use a third-party domain name registrar, who will typically charge a small annual fee.
