  • Article
  • 3 minutes to read

You can configure Azure DNS to resolve host names in your public domain. For example, if y'all purchased the contoso.xyz domain name from a domain proper noun registrar, yous tin configure Azure DNS to host the contoso.xyz domain and resolve www.contoso.xyz to the IP address of your web server or spider web app.

In this quickstart, you will create a test domain, and then create an address record to resolve www to the IP address 10.10.10.10.

Important

All the names and IP addresses in this quickstart are examples that do not represent real-world scenarios.

If you don't take an Azure subscription, create a gratuitous business relationship earlier you begin.

For all portal steps, sign in to the Azure portal.

Prerequisites

  • An Azure account with an agile subscription. Create an account for free.

Sign in to the Azure portal

Sign in to the Azure portal with your Azure account.

Create a DNS zone

A DNS zone contains the DNS entries for a domain. To start hosting your domain in Azure DNS, you create a DNS zone for that domain proper noun.

To create the DNS zone:

  1. At upper left, select Create a resource, and then Networking, and so DNS zone.

  2. On the Create DNS zone page, blazon or select the following values:

    • Name: Type contoso.xyz for this quickstart example. The DNS zone name can be any value that is not already configured on the Azure DNS servers. A real-globe value would be a domain that you bought from a domain proper name registrar.
    • Resource grouping: Select Create new, enter MyResourceGroup, and select OK. The resource group name must be unique within the Azure subscription.

  3. Select Create.

Information technology may take a few minutes to create the zone.

Create a DNS record

You create DNS entries or records for your domain inside the DNS zone. Create a new accost tape or 'A' record to resolve a host proper name to an IPv4 accost.

To create an 'A' tape:

  1. In the Azure portal, under All resources, open the contoso.xyz DNS zone in the MyResourceGroup resource group. You lot can enter contoso.xyz in the Filter by proper name box to detect it more easily.

  2. At the top of the DNS zone page, select + Record set.

  3. On the Add record set page, type or select the following values:

    • Proper name: Type www. The record name is the host proper name that y'all want to resolve to the specified IP address.
    • Blazon: Select A. 'A' records are the most common, simply in that location are other record types for post servers ('MX'), IP v6 addresses ('AAAA'), and and then on.
    • TTL: Type 1. Time-to-live of the DNS request specifies how long DNS servers and clients tin can cache a response.
    • TTL unit of measurement: Select Hours. This is the time unit for the TTL value.
    • IP address: For this quickstart instance, type 10.10.ten.10. This value is the IP address the record name resolves to. In a real-world scenario, you would enter the public IP address for your spider web server.

Since this quickstart is merely for quick testing purposes, there's no need to configure the Azure DNS name servers at a domain name registrar. With a real production domain, you'll want anyone on the Internet to resolve the host proper noun to connect to your web server or app. Y'all'll visit your domain name registrar to replace the proper noun server records with the Azure DNS proper name servers. For more information, see Tutorial: Host your domain in Azure DNS.

Exam the proper name resolution

Now that you take a test DNS zone with a examination 'A' record, you lot can test the proper name resolution with a tool called nslookup.

To examination DNS proper name resolution:

  1. In the Azure portal, under All resource, open the contoso.xyz DNS zone in the MyResourceGroup resource group. You can enter contoso.xyz in the Filter past name box to observe it more hands.

  2. Re-create i of the name server names from the name server list on the Overview folio.

    zone

  3. Open a control prompt, and run the following command:

                      nslookup www.contoso.xyz <name server name>

    For instance:

                      nslookup www.contoso.xyz ns1-08.azure-dns.com.

    Y'all should see something similar the following screen:

    Screenshot shows a command prompt window with an n s lookup command and values for Server, Address, Name, and Address.

The host proper name www.contoso.xyz resolves to 10.10.10.10, just as you configured it. This result verifies that name resolution is working correctly.

Clean up resources

When you no longer need the resource you created in this quickstart, remove them by deleting the MyResourceGroup resource group. Open up the MyResourceGroup resource group, and select Delete resource group.
