Root domain in Azure FrontDoor configuration - azure

I am trying to set up the routing for the Apex/root domain of my website(myrootdomain.eu) in Azure FrontDoor.
Reference :https://learn.microsoft.com/en-us/azure/frontdoor/front-door-how-to-onboard-apex-domain
Crated the Alias record with #.myrootdomain.eu in Azure DNS against the Azure resource as FrontDoor. A CNAME was created like this : afdverify.myrootdomain.eu
When i try adding the custom domain(myrootdomain.eu) into the frontend host of FrontDoor, it is giving the error CNAME record is not found. What additional step is required here .
Is there any setting or mapping to be done in my DNS 123domain or frontdoor for this domain : afdverify.myrootdomain.eu
What should be the mapping in domain provider (123domain in my case) for the naked domain(myrootdomain.eu) ?
Could not find any thing about that in the reference doc.

If you have hosted your domain in Azure DNS, (that is to edit the NS records and replace the NS records with the Azure DNS name servers in the registrar's DNS management page), you do not need to map in your original domain provider. It takes just a few seconds on my side to wait for the DNS taking place for the Apex/root domain in Azure Front Door.
After creating an alias record for zone apex, it creates a zone apex record pointing to your Front Door resource and also a CNAME record mapping 'afdverify' (example - afdverify.contosonews.com) to afdverify.<name>.azurefd.net.
If you have finished the above steps correctly, it usually takes some time for DNS propagation, you could check it via whatsmydns or viewdns. As the comment said, you can check if the CNAME is effective or not using nslookup or google dig tool.

Azure DNS Zone - unable to find CDN endpoint in list when adding record

I've setup a static site with Azure WebsiteCDN with custom domain, which works correctly for www.mysite.com
Now I'm trying to create an alias record set in DNS Zones (to point to apex domain) however the list is always empty:
Any ideas why it doesn't show up?
Mapping your apex or root domain to your CDN endpoint basically requires CNAME flattening or DNS chasing. There are other DNS providers as well that support CNAME flattening or DNS chasing, however, Azure CDN recommends using Azure DNS for its customers for hosting their domains.
Refer : https://learn.microsoft.com/en-us/azure/cdn/onboard-apex-domain
If you are using a different provider than Azure DNS, then you would need to contact the DNS provider and check if they support CNAME flattening or if there is any way to achieve this on their end.
If it is not supported with your DNS provider, then you could delegate your domain to Azure DNS and manage your DNS records in Azure DNS and here you will be able to create an Alias record which will help you onboard your apex domain to Azure CDN.
Please refer : https://learn.microsoft.com/en-us/azure/dns/dns-domain-delegation
https://learn.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns
While selecting the CDN resource in alias record set, make sure you have selected the subscription in which the CDN endpoint is deployed.
Important Note : Pointing a zone apex to CDN endpoints for Azure CDN from Akamai is currently not supported.

Why Azure DNS Zone create afdverify subdomain automatically and how to stop?

I create a CNAME record in DNS ZONE (e.g: site1.example.com). And then, afdverify.site1.example.com and site1.example.com will be created.
I just want to create site1.example.com only.
• #Kyakya, from your query and the screenshot, I can understand that you are trying to create a CNAME record for the ‘site1.example.com’ URL. But when creating a CNAME DNS record in a DNS zone, you will have to mention its alias FQDN URL, i.e., that original URL which you are trying to mask or associate with by creating this CNAME record. Thus, I can understand from the screenshot that you are trying to create a CNANE record for the Azure front door URL in DNS zone in Azure.
As a result, when you create a CNAME record with a custom domain name for an already hosted URL, you need to ensure that the original hosted URL is reachable and available as the CNAME record created will only redirect the DNS requests to the original hosted URL only.
• Since, in your case, you don’t want to create a subdomain regarding ‘site1.example.com’ in your DNS zone, i.e., ‘afdverify.site1.example.com’ so in that scenario, you will have to create an ‘A’ host record for the ‘site1.example.com’ in your public DNS server where your basic custom domain ‘example.com’ is registered. Once done, then create a CNAME record for the inbuilt Azure generated FQDN of that resource in your public DNS zone in that DNS server with ‘site1.example.com’ that you want.
And if you don’t want that too, then you will have to verify your custom domain in Azure, and then create resources in Azure based on the records created in DNS zone provisioned.

Azure Front Door and DNS Configuration

I'm having issue configuring my DNS to make all traffic routed from the root domain (no www) to the Azure front door. The below is what I have done so far:
Create the front door (frontend/backend/routing)
On-Board my custom domain (let's say hello.com) on front door
Now as per Microsoft guide I have to add a CNAME record to the DNS hosting provider (domain.com) to route the traffic to front door. But I have been told by domain.com that I cannot have A record and CNAME record named #
So I've found this solution https://learn.microsoft.com/en-gb/azure/frontdoor/front-door-how-to-onboard-apex-domain
Then I have created a DNS Zone on my Azure environment named "hello.com" and followed the guide.
Still I cannot see the traffic going through the front door.
Is that because I have 2 DNS servers? (one hosted on domain.com and another one on Azure)?
Can It be propagation time ?
Also how does azure know that I'm the owner of hello.com domain ?
As the linking document, to onboard a root or apex domain on your Front Door, you could use alias records in Azure DNS.
There are other DNS providers as well that support CNAME flattening or
DNS chasing, however, Azure Front Door recommends using Azure DNS for
its customers for hosting their domains.
If you select to use Azure DNS to host DNS domains, first you need to create an Azure DNS zone (hello.com) in Azure and delegate the domain to Azure DNS via changing the name server records for the domain in your original DNS registrar. You can verify the delegation by using a tool such as nslookup to query the Start of Authority (SOA) record for your zone. It can take up to 72 hours to propagate worldwide, although it typically takes a few hours.
Then, you can add an alias record for the zone apex in the DNS configuration for the domain to be onboarded. After this, you can add the apex domain name in the custom host name field on the Front Door designer tab.
To access your backend web app with the custom domain, ensure that you have created appropriate routing rules for your apex domain or added the domain to existing routing rules. Or, you may enable HTTPS on your custom domain.

Azure DNS CNAME records

I am trying to configure Auth0 custom domains with my azure web application. It is asking for a CNAME Record to be set.
I set this up in azure with a provided dns name, and set up the values as such:
but the verify button still does not work. i heard you may need to wait a few days for it to settle, but i waited all weekend with no luck. i saw in this post i may want to remove the NS and SOA types?
Wildcard and Naked CNAME records in Azure DNS
how can i verify this domain
As far as I know, you can not use the domain *.cloudapp.azure.com as the custom domain for your Auth0 as it is owned by Azure. You need to purchase a domain from the domain provider like Godaddy to configure your custom domain. Then you could validate that domain ownership.
You can't use Azure DNS to buy a domain name. Azure DNS is a hosting service for DNS domains that provides name resolution by using Microsoft Azure infrastructure. It's not necessary. You can selectly host your domain in Azure DNS.

How to create custom wildcard domain in azure

I'm having an issue with setting a custom wildcard domain on an Azure Website.
The azure website is demo.azurewebsites.net
And my custom domain is tenant1.demo.azurewebsites.net
I have done following steps : --
Step A:- Login into the portal.azure.com
Step B:- Then created zone with the following steps.
In this I filled all required information and select resource group as use existing. Because I have existing resource group. And click on create button.
C) After click on create button of above image it will show following image.
D) After that I crated record set. Please refer following image. I filled all information that required.
Name = *
Type = CNAME
TTL = 1
TTL unit = Hours
Alias = my existing domain
E) after that I created custom domain.
When I am going to create custom domain it show following error.
And my custom domain is tenant1.demo.azurewebsites.net
We can’t add subdomain to azurewebsites.net, because we are not the owner of azurewebsites.net.
Step B:- Then created zone with the following steps.
Until now, Azure doesn’t provide domain register service. Azure DNS Zone is used to host the DNS records for a particular domain. Azure DNS Service will answers DNS queries for records in the zone. It works as a name server. The prerequisites to use Azure DNS Zone is that you must be the owner of the domain. Please check the following note from Azure DNS Zone official document.
You do not have to own a domain name to create a DNS zone with that domain name in Azure DNS. However, you do need to own the domain to configure the Azure DNS name servers as the correct name servers for the domain name with the domain name registrar.
After you create a DNS Zone, to let the DNS record works, you also need to delegate your domain to Azure DNS by adding name server record in your domain register portal. Though you can add DNS record for demo.azurewebsites.net in your DNS zone as you mentioned in your post. But it won’t work until you have the right to configure the name server record in your domain register portal.
