How do I add a second domain name to my primary domain using the Azure DNS?

Terence Chase 0

I have my domain and DNS zone set up on Azure. I just bought a .net extension for one of the web sites. Now, there is no clear explanation on what to do now. I have used the existing nameserver of the primary domain. When I added the custom domain name to the azure active directory, it gave me a new TXT entry, which I added to the existing domain.

In one direction, the articles and videos I have seen suggest I add a CNAME entry, but Azure DNS won't let me add a "@".

Can someone let me know what is wrong, or suggest a working solution?

Thank you.

There is nothing that a screenshot can provide that my explanation already has.

I am trying to find out how to add domain.ca to one that is domain.net. I want both to point to the same location. I have created a DNS Zone for domain.net using Microsoft Azure. I have added the domain names to through 'Custom Domain Names" on the Microsoft Entra ID.

Now, Azure won't let me create a separate CNAME record, and I added the TXT reference to the existing record hoping it would be seen, but it doesn't look like it. On the web site, the new domains just show as unverified.

I did get this one thing inside custom domain name. To use domain.ca with your Microsoft Entra tenant, create a new TXT record with your domain name registrar using the info below. My registrar is with Godaddy and it is using the nameservers used by domain.net.

I have tried lots of different keytword searchs to find a solution to this. So far, no luck. Can someone direct me to a site that will show me how to do this properly?

"To add a second domain name to your primary domain using Azure DNS, you need to create a new DNS zone in Azure for the secondary domain and then configure the appropriate CNAME records to point the new domain to your primary domain's IP address within the Azure DNS management portal; essentially, you're creating an alias for your primary domain using the new domain name."

Do I create a new DNS Zone with the domain.ca, and then point that at the existing record? Since it is Azure, what IP address would I use?

To add a second domain name to your primary domain using Azure DNS, you need to create a new DNS zone in Azure for the secondary domain and then configure the appropriate CNAME records to point the new domain to your primary domain's IP address within the Azure DNS management portal; essentially, you're creating an alias for your primary domain using the new domain name.

When I try to create a CNAME record, I get this error when I try to create "@":

Each label must only contain letters, numbers, underscores, and/or dashes. Each label should be separated from other labels by a period. A wildcard ('*' character) is permitted either as the single character in the name, or as the first label in the name. An empty value, or a single '@' character is permitted for record sets at the zone apex (except for CNAME record sets).

Hello Terence Chase,

We appreciate your patience!

Yes, you cannot add a Cname record at "@" level.

NOTE: It's not possible, this is called a root domain, you cannot have a root domain at azure Unless and until you are using azure services.
When you are using your own websites, then it won't support adding a record at root domain level you can only add an "A" record at root Level.

You can only a create an "A" record at "@".

If you have any further concerns, please do not hesitate to contact us.

We are pleased to help you.

I look forward to your response and appreciate your time on this.

In other words, there is no way to point the new domain extension to the primary domain without an IP address. Using an A record directs the new traffic to the web site, which I guess was the point.

Thanks, I think. It is a solution, just not the one I expected.
